I recently built a computer and I plan on buying Starcraft 2. I want to be able to play the game well at max graphics + AA @ 1920 x 1200 with a decent framerate. I am looking to spend < 200$ and have been looking at the 4870 and the 260. Would these cards be able to do what I need? Should I wait and get a DX 11 card? (I don't think starcraft 2 uses DX11) I only really plan on playing Starcraft 2. Any help is appreciated!
