Thanks for the replies. Ill have to check out some of the cards that were linked.
2 GB of VRAM is more then enough for 1080p, heck its more then enough for 1600p (2560x1600 which I have). The VRAM only becomes a real bottle neck when you go beyond a single 120Hz monitor, i.e. triple 3D screens. Unless you have a triple monitor setup for gaming, you DO NOT need more then 2 GB of VRAM.
I played Crysis, 2, 3 all at 2560x1600 with a GTX 690 which only has 2 GBs per GPU, nothing has ever gotten close to maxing out my VRAM. Then again, I also do not play with a stupid amount of Anti-Aliasing, just a minor level of AA is enough.
If you can order from AmazonUK take a look at the Sapphire 7950 with 3gb ddr5. They are on sale at Amazon USA, these cards are a beast.
There are a few games that will hit the 2GB mark @ 1080P, but they are in the minority. (Metro springs to mind)
But yep, 2GB is certainly adequate - even with triple screens. 2GB hasn't really been an issue for me either as long as the AA is reasonable like you said. Having a 3GB card isn't really going to be a magic FPS bullet.
OP, you're still going to have lower a few details anyway - but for the best chance of higher visuals with the highest FPS, aside from the extra Vram, a gtx 660 isn't really that much of an upgrade from your 570.
A gtx 760, 770 or 7970 is what you really need to be looking at for the best quality and gameplay.
