RTX 3080 or 3090 Advice Required

Hi,

My son is learning to fly and his flight school have suggested getting him setup with MS flight sim which made me think should I step up and get a 3090 and start crypto mining or stick with 3080 and forget mining.

Are there any cards I should look at?

Any suggestions or advice would be great.

Thanks.

  • 3080 can also mining.
    3060ti can also run with MS flight SIM, 4k 30fps for slow plane or lower it down to 1440p/1080p for higher fps.

  • I’d say 3080Ti, you can grab them for under $2.5k if you look hard enough. Congrats!

    LHR Mining isnt so bad on the 3080, you can use something like nicehash and still make about 6 dollars a day.

    I'd suggest he runs DCS instead of flight sim. Flight sim is a simulator in name only. It's a game. DCS has intense realism.

    isn't a 3090 just a 3080 that cost ~40% more but is only ~25% better?

    are you sure you can't run flight sim on a 3080? I get the game is demanding but i would be surprised if you can't.

    you can certainly mine on both. with just the default quickminer settings I've been doing on average $8/day on my 3080 for the last 3 months and that's in my main gaming and work computer so the airflow is not great. in fact i remember reading somewhere that 3090 is less efficient and often has cooling problems worse than the 3080.

    I'd say go for a 3080 because its a more efficient purchase and should still get you what you want. only if you are sure you need a 3090 would i get one.

    Edit - also forgot to mention you can safely run a 3080 on an 750w power supply, but i think the manufacturer recommends at least an 850w power supply for the 3090 and you will need a newer one with enough cables, an old model may not have enough cables. so its likey buying a 3090 will also mean an additional expensive upgrade because you also need to buy a new 850w power supply. (don't quote me on the exact wattage all i know is that for my 3080 i was told i need a 750w to be safe and obey all the recommendations.)

    • Problem is you can't buy a FHR 3080 anymore except by paying a fortune on the used market. All the 3090s are still FHR.

      Although I'm not sure how the LHR 3080 goes with alt coins, some seem to do pretty well.

      • oh i see. according to this website which obviously varies a lot but i found on average seems pretty accurate from my own experiences: https://www.nicehash.com/mining-hardware, the lhr model mines 75% as well as the fhr 3080 so your indecision makes a lot more sens to me now. but i guess it all really depends on what sort of deal you can get. definitely would still consider a 3080 if you can get a decent deal though.

        nobody knows what will happen when eth2 starts though so i would just focus on getting the cheapest card that will run the software that you want to run properly. personally i wouldn't be surprised if gpu mining takes a decent hit to profitability so it ends up more like hard drive mining where the return on investment is more like 2 years than 7 months.

  • What? turn down the settings… graphics aren't everything

  • I run MSF2020 on a 4K VR headset(Reverb) smoothly with a mere 1080. 3080 is fine.

    Also MSF2020 is good for GA, but he wants to practice flying airliners then XP11 is much better.

  • Don't bother, 3090Ti is gonna be out in another two months or wait a few months longer and the 4080 and 4090 comes out.
