2GB card...
It's a last generation card...but properly overclocked...you should be able to play most games on ultra...
Your card still can't handle the big boy games though...Crysis 3 and Far Cry 3 will eat that card up...I bet you wouldn't be able to get 30fps on those games if they were just set to high...
I also wouldn't try to go above 1080p with that card...
Not a bad introduction into the master race though...you got to start somewhere
And if you got it for cheap and your PC can handle it SLI is always an option...
And as always there's more to gaming than just a good graphics card...games only run as smooth as your bottleneck...so be sure you have decent RAM and a CPU as well...CPU not so much but games are starting to take advantage of more than 2 cores now...
