Ghetto upgrades or full replacement? - Optiplex 9010 GPU
So I've got the classic Optiplex 9010, with an i7 3770 and 16Gb RAM paired with a low profile 1050Ti. It's been serving me pretty well for my modest gaming needs, but running through Gears 5 recently was seemingly causing some hiccups and I think I've about hit my limit at 1080p.
However, my next upgrade will be the WQHD Kogan 34"… and at 2560x1440 (plus the other monitors) I'm nervous that I'm gonna be running at 20fps or less on most games simply due to the sheer quantity of pixels. Hence I'm debating a GPU step-up, which would also mean a second PSU (I have no issues with this at all, I have the hardware & experience)) or just go for a whole system upgrade instead. Budget is fairly constrained at $500; hence the consideration on put it all on the GPU.
First question - the 3770 seems to hold it's own rather well when comparing to the newer gen CPUs, and the 16Gb RAM seems more than adequate. Is there any solid reason to upgrade the rest of my box? Or any other advice on this?
Second - Irrespective of upgrading the rest, what's the current sweet spot for GPUs? I have no loyalties, and given the Kogan will have Freesync (plus G-Sync compatibility) then I'm happy to go for the best value option. Is AMD currently leading for mid-range GPUs?
