Hi,

Looking to custom build a pc with the below requirements. Could anyone please provide your inputs/advise?

Primary purpose: General office related work (Remote desktop, Microsoft office, etc). Not for gaming. I don't game at all.

Secondary purpose: Build few VMware virtual machines for office related lab purposes.

Budget: Preferred: $1500. Maximum: $2000

Monitor(s): Looking to buy two LG 27UD68 4k monitors for dual monitor setup. Need an appropriate graphic card for just to run the monitors at 60hz.

OS required?: No

Graphic Card: Was looking at this graphic card for the dual 4k monitor setup, but unsure if it is an over kill – https://www.amazon.com/dp/B01GX5YWAO/

Was also looking at this to see if it is enough to run dual 4k monitors – http://www.newegg.com/Product/Product.aspx?Item=N82E16814126…

Peripherals required: Already have keyboard, mouse, headphones, speakers.

Re-using parts?: Already have 500GB SSD and a few SAS drives (1TB, 2TB) lying around. So don't need hard drives.

Overclocking?: No

Aesthetics/preferences?: None

Extra Information:
Looking for a PSU that drives the graphic card to drive the 4k monitors (two planned for now. May be three or four in future). Also make the pc future proof. At least so that I don't have to look upgrading the pc for the next 5 years. Lastly, THANK YOU SO MUCH for reviewing and providing inputs/feedback. Really appreciate your help.

UPDATE# 1: Looking at this spec now http://au.pcpartpicker.com/user/gopi_kv2004/saved/64NNGX

    RAM - 16GB
    Hyper-Threading - i7 6700 (or 6700K if you're going to overclock)
    Graphics Card - Yours looks fine

    Sorry for the very, very brief comment. But I guess the MoBo and others shouldn't be too hard.

    • vankaaye on 29/09/2016 - 13:23

      Thanks BobbyJ.

      Do you have any specific make & models that I can look in to?

      Which graphic card you were referring to, the Amazon one or the Newegg one?

      • BobbyJ on 29/09/2016 - 14:29

        Sorry, not too sure of specific make & models. Also, didn't realise you listed two graphics cards derp. They are completely different cards, in two completely different tiers. Also, I don't know how well the 460 does at pushing multiple 4K screens. So sorry, can't help you there.

        EDIT: Keep in mind the following if you're buying a 6000 series (skylake) CPU:

        • You'll need an LGA 1151 Socket Motherboard
        • You are much better off getting DDR4 RAM not DDR3

        Ask around on Whirlpool as well. Check out their PC Build Suggestions. The $1500 ($1900) one on this page seems perfect for you.

        • vankaaye on 29/09/2016 - 15:57

          Thank you. Will have a look.

          @gopi_kv2004:
          Looks fine I guess.

          1) I'm not too sure about the RAM compatibility. Someone else should be able to confirm that.

          2) It outputs 4K at 24hz over HDMI. But then again the resolution on Asus's website is different to what your monitor will output. Again, I'm sure someone else should be able to confirm that it can ouput 4K at 60hz at your monitor's resolution.

        • vankaaye on 30/09/2016 - 18:58

          @BobbyJ: Thanks for reviewing. Trying to use the USB - C to Displayport cable for the second 4k monitor @ 60hz

    Why are you using 4K? Is it actually doing anything useful because frankly Windows has issues providing a good 4K experience which I wouldn't want if i was only using my computer for office work and web browsing. If I was gaming or editing images or video 4K may make more sense.

    Also I could be wrong but won't some motherboards + cpu power 2 4K monitors without needing additional video cards?

    And even if that is not the case why are you buying a current generation video card if you have no plans to use the computer for games?

    • Cheap Charlie on 29/09/2016 - 13:57

      Also I could be wrong but won't some motherboards + cpu power 2 4K monitors without needing additional video cards?

      I think this is a good point. Skylake spec onboard graphics may be all you need?

      As bobby mentioned, 16GB of ram and a 6700 would be a solid platform.

      • vankaaye on 29/09/2016 - 14:00

        Thanks for some direction with those onboard graphics. Will have a look. Any specific make or models for RAM, CPU and Motherboard?

          Looks like there are a few good suggestions coming in below now

        • vankaaye on 29/09/2016 - 16:00

          @Cheap Charlie: Looks like Skylake ones can do 3 x 4k@60hz with normal workload, but may struggle when watching 4k content. I might start of with the on-board capability and then upgrade to a GPU if needed.

        • Cheap Charlie on 29/09/2016 - 16:32

          @gopi_kv2004: Thanks for the update.
          Are you able to expand on your likely requirements in terms of virtual machines?
          As some of the guys are mentioning, the more VM's the more cores and more RAM is required to effectively run them.

          Monitor(s): Those LG 27UD68 4k monitors are fine. Will eat a fair bit into your budget

          Graphic Card: Run with Skylake CPU onboard for now

          CPU: Again your VM requirements will determine your direction here. As a minimum perhaps a quad core (8 threds) i7 6700. Based on previous offers around $330 - $350 https://www.ozbargain.com.au/search/node/6700

          RAM: Your demands in terms of VM's will need to be taken into account here. Based on recent offers 16GB of DDR4 (suit skylake) will run you around $100. 32Gb will run you $200 with change Reference: https://www.ozbargain.com.au/search/node/DDR4

          MOBO:
          - LGA 1151 socket (suits Skylake). Considerations include SATA ports, IO (given you are using onbaord, consider how you want to connect your monitors HDMI preferred, DVI VGA etc)
          - Form factor: What size tower suits your requirements?
          - M.2: Required?
          - Wifi: Required?
          - RAM: How many Rams slots are required?
          - NIC: Do you require multiple Ethernet interfaces?
          - PCIe: Required? You may add a GPU down the track or new tech memory?
          Example Price points: http://www.newegg.com/global/au/Product/ProductList.aspx?Sub…

          There are several sites which collates your build parts together online which can then easily be shared.

          @Cheap Charlie:

          how you want to connect your monitors HDMI preferred, DVI VGA etc)

          He'd need to have two HDMI ports or Display ports since DVI only outputs up to 2560 x 1600.

        • Cheap Charlie on 30/09/2016 - 14:36

          @BobbyJ:
          Excellent point.
          I mentioned DVI as the OP was considering 1080P based on issues relating to Windows 10.
          HDMI preferred, however in the event a MOBO came up which was limited to 1 x of each video output at the right price, this may not be a deal breaker for the OP in the event he did decide to run with 1080P.

        • vankaaye on 30/09/2016 - 16:59

          @Cheap Charlie: Based on your and some of the advises from others here, looking at the below spec.

          http://au.pcpartpicker.com/user/gopi_kv2004/saved/64NNGX

          Could you please review this and share your thoughts?

          Regarding the virtual machines, trying to build a few vms in future. 16GB RAM should be fine for now I reckon.

          Couldn't find decent prices for the parts I am looking for when compared to some past deals here on ozbargain.

        • Cheap Charlie on 01/10/2016 - 12:17

          @gopi_kv2004:
          My thoughts;

          • Adequate Sata 3 points to suit your SSD/HDD requirements on that mobo?
          • Thinking in relation to your monitors. If you are sticking with 1080P, perhapps consider the Asus VC239's (Saw these as part of the eBay 20% off deal around the $17X mark each inc exp shipping.
          • This may come in handy for comparing like components performance wise with those on your preferred shopping list. Ie you would jump on a sharp deal on say a 6600K CPU

          Couldn't find decent prices for the parts I am looking for when compared to some past deals here on ozbargain.

          It a matter of timing.
          Options
          (a) Buy all your components from a single supplier at today's prices
          (b) Are you in a position were you can acquire all your components over a couple of months (jump on components as individual offers of like components come up)
          (c) Hold out for a eBay 20% offer

          Are you in a position were you can purchase components offshore or are you needing a Tax invoice with an ABN for accounting purposes?

        • klaw81 on 07/10/2016 - 12:35

          @Cheap Charlie:
          That PSU is massively over-sized. A 6700K needs a bit of juice, plus it's a good idea to leave room for a future GPU, but 550W is heaps enough and lots cheaper.

        • Cheap Charlie on 07/10/2016 - 12:49

          @klaw81: True, I recommended that option as the OP noted future proofing the unit and the OP was considering a EVGA SuperNova 750 G2.
          If you dug into exactly what the OP will actually use the PC for you could dial every thing back including 4k monitors.

    • vankaaye on 29/09/2016 - 13:58

      Thanks for the response.

      Been hearing that windows isn't so good with 4k monitors at this stage. But just trying to future proof my one off purchase in the next 5 years with my monitors. Till windows get better with 4k monitors, may just use a lower resolution or scaling.

      Not sure if a good motherboard + cpu itself would be enough to run 2 x 4k monitors at 60hz. Searched a bit, but couldn't find. Love to hear from anyone though.

      Not fancy about any newer/recent graphic cards. Anything that will power the dual 4k monitors and will run for few years would be good. And again, trying to future proof as much as I can. Thanks again for your response.

    I you are looking at running miltiple vmware virtual machines at the same time then you are better of with Xenons.
    You could opt for dual processor but its going to cost you a lot.
    My workstation in a dual xenon (6 physical core/ 12 with hyper threading) and 48 GB RAM(ECC).
    It was a used Dell Precision T5xxx and its about 4 yrs old now and will be good for another 2-3 years.
    I cost about $1200 for the full setup. A similar new one was costing about $4000. So I went with used due to budget restrictions.
    I use it to run some work related application which are heavy on multi threading.

    Desktop processors are good for gaming but not for running multiple virtual machines.

    • BobbyJ on 29/09/2016 - 14:28

      I know this used to be the case with Xeon's. But, apparently they're not that good anymore compared to the Skylake processors. I'm not too sure though, so correct me if I'm wrong.

      • apple2016 on 29/09/2016 - 14:55
        +2

        Yes, with Skylake processors the difference in specification is not much.
        But the processor/motherboard/chipset that you use would make a lot of difference during multi processing.
        At least this is what I have seen.

    Don't fluff around with anything other than workstation GPU's. They are designed to run multiple monitors at 4K/60Hz.

    Why do you want 4K? If you want to use it for movie content, just buy 1 and get 2 ultra-wide monitors.

    You won't get much 'ofice work' benefit from a 27" UHD monitor. You'd be better off with 2-3 27-29" ultra-wide monitors (eg 29UM68-P) or 3-4 24-27" standard monitors. Cost will be about the same as you have budgeted and you won't need a high-end graphics card to drive them. This configuration is much more usable for office work if you have the desk space.

    • vankaaye on 30/09/2016 - 16:52

      Not sure if I quite got the setup you are referring to. I am looking for a possible dual monitor side by side setup.

      • dfr on 07/10/2016 - 18:02

        Sorry, for some reason I thought you wanted triple monitors.

        My point is that I think you are better off with ultra-wide monitors rather than 4K for general office work. The DPI will be too small on a 27" @ 4K, go check it out at a store. You will have more usable screen space with 29" or 34" Ultra wide monitors.

  • he3at on 30/09/2016 - 17:32

    I'll weigh in on your GPU cos I've just bought one with the same use case as yours (no 3D gaming).

    This Asus R7-250 http://www.msy.com.au/pc-components/17578-asus-r7250-2gd5-2g… is $99 at MSY and drives my Phillips BDM4065UC at 4k 60Hz over Displayport just fine. I can only get 4k24 out of the HDMI port, but not sure if it's the cable or the card itself. It's powered entirely from the PCIe bus and no extra power lead is required.

    No idea if it will drive the second monitor at 4k60 as I only have one 4k monitor, but at $99 you could just buy a second GPU if required.

    Make sure you don't cheap out on the cables and get proper DP1.2 certified cables. I've had good results with Alogic DP cables.

    • BobbyJ on 30/09/2016 - 18:43

      Do you know if you could use both the graphics card and on-board? So have one monitor hooked up to the card and another to the MoBo?

      • vankaaye on 30/09/2016 - 18:58

        Yeah, you can.

    • vankaaye on 30/09/2016 - 19:00

      Yeah, that is my backup option if the onboard is not up to the mark with two 4k displays running one from the displayport and the other from USB - C, both at 60hz

  • donnot on 30/09/2016 - 20:46

    No need to go for the EVGA 750 G2- 650W would be plenty so unless you're planning on running multiple graphics cards, the 650 G2 would be a better option IMO. The fan is significantly louder in the 750 (39.9db vs 27.7 in the 650). Other than that, not much of a difference apart from wattage.

  • brotherfranciz on 03/10/2016 - 11:31

    Sorry for responding to an old-ish topic, but I am somewhat bemused that you would need dual 4K monitors for general office related work (as well as an i7?!)… To be specific, I am bemused at the "4K" bit, not the dual monitors.

    You say it is to future proof your PC, but why would you need to future proof for 4K if it's only for general office related work? I don't see any uses for 4K other than for gaming, movies, multimedia editing and the like.

    The i7 is also overkill for general office related work. It's way overpowered unless you are doing processor-intensive work.

    Dual monitors are awesome, but you could save a pretty penny by opting not to get 4K monitors and also going with an i5 (or even an i3).

    • vankaaye on 03/10/2016 - 11:35

      Appreciate your feedback brotherrfranciz. Future proof in the sense, two years ago I never thought I would need a 4k monitor and bought something which is not compatible with 4k. The i7 and 4k are something for which I am sort of happy to spend a bit more now rather than spend more later to replace the i5 and non 4k monitor if I see the need. You never know what is out there in 2 years time, even this 4k and i7 would not be compatible by that time :)

      I bought 2 x 75" Full HD TVs for $4,000 each an year ago. I repent everyday when I see these 4k TVs on sale. I would rather have spent that extra thousand or two to get the 4k instead.
