canadianvice :
I'm looking into this as I may wish to get some nice 2K monitors, but what sort of VRAM requirement would I have to satisfy? I tend to like playing on higher settings, but about the most graphically intensive game I have/would have is GTAV.
Also, does anyone have any good GFX recommendations at a good price? ($ CAD)
My preference would be to source from Memoryexpress.
3gb should do alright. generally speaking you need a BARE min of 3gb of vram for 4k, in reality 4gb of vram is probably required for 4k, as it's clear nvidia 3gb cards like the 780ti suffer a bit in 4k while 4gb cards like the r9-290x do pretty good in it. i'd say 3gb should be fine for 1440p
As for best card for 1440p right now?
on the low end a GTX770 or r9-280x could game respectfully in 1440p. though i'd stick to the r9-280x it tends to do a bit better at that resolution, particularly with recent titles which use more then 2gb of vram. That old card is still a beast, and a steal at the $220 price-point it's available at in the states. Understand though, while you could play everything in ultra in 1080p with that card, you'll probably have to play the latest and greatest games in medium/high in 1440p with it. so it's not "great"
the next cards would be the r9-290/r9-290x or GTX 970. Personally i'd probably go with the GTX970 based on noise/heat concerns alone. Understand i'm not an nvidia fanboy, the last 4 gpus I've owned have been 2 nvidia, 2 amd, including an r9-280x. The reality of the matter is if you're planning on gaming in 1440p, the GTX970 is a no brainer. It's a little faster then the two AMD cards (at that resolution), and being a 145W TDP uses half the power... frankly, my current GTX970 doesn't even spin up it's fans when gaming most titles i own. Very quiet, very cold, semi passive. It's a nice card. It's also made, just like the r9-290/290x to pretty much max games in 1440p. frankly spending more then this at 1440p is a bit of a waste of cash, as these 3 cards should max pretty much everything in 1440p
overkill would be the GTX980/TitanX.
