Assuming you have a 1.2gb 570 I would give it a miss.
Adding another one will give you a serious power boost, but sadly the way things are headed it will be useless power.
I took those measurements playing Battlefield 3 in single player yesterday. They are VRAM usage levels.
I've seen stats from users playing it in multiplayer where memory usage has gone over 1600mb.
I run quad SLI and it has some serious muscles. Sadly when I load BF3 it all falls to pieces, because even though I can whack out 3D scores in Vantage well over 30,000 896mb VRAM simply isn't enough.
There's a reason AMD's new cards have 3gb, and it's not for show. It's for the whacking huge textures going into modern games.

Crivens I just noticed that. Is that a joke?
Anything more than a 560ti is complete and utterly wasted at that resolution. Infact, the 7970 doesn't really come into its own until you get it to 2560x1600.
