And its still more than enough at 1440p. I'd personally know it because I've easily used SLI GTX 670 2gb for 1440p, and the VRAM made little difference in performance. So please, stop spouting this crud.
i stated my reasons. I believe they are very pertinent. VRAM is important. remember how the GTX 570 was a powerful card but was VRAM limited. BF3 with 4x MSAA was one such case where GTX 570 was powerful but VRAM limited.
"The GeForce GTX 570 did not do as well in this game, we were only able to turn on FXAA at 1920x1200. When we tried to enable 2X or 4X MSAA the game was laggy and unplayable. We also tried 4X AA on the Radeon HD 7870, and were pleasantly surprised to find out that it was almost playable"
with next gen consoles and games around the corner 2GB might be cutting it a little too close. An avg clocking HD 7950 at 1150 mhz performs very well even against an avg GTX 680(1250 mhz) . but when you run out of VRAM the game becomes unplayable and you have to reduce settings.
Heck, the only reason I moved up to the 7970s is purely because I plan on a second/third 1440p screen. In that case, yes you'll need the VRAM.. But even at a single 1440p, 2GB of VRAM is easily enough. EASILY.
And a game will be bought, played, and thrown away far faster than a GPU. You should NEVER use a game as an excuse for a lower performing card. In the end, you are left with a game that will end up sitting in your Steam library, unused after 4 months, and left with the lower performing card if you go with the HD 7950.
the fact that HD 7950 comes with 3 games, one of which could be BF4 which the OP intends to play
is important. also even otherwise the HD 7950 comes with 3 games which can be sold. so the price diff is more than the listed price.
