You need a kickass processor to play SCII maxed out, but only if you are playing 4v4. If you are gonna play 4v4, a lot of the crazier custom games (like the survival ones against zerg rushes) or FFAs, I'd recommend the AMD Phenom II X6 1100T. Gets about 25 fps in maxed out battles. Averages 140. If not that one, then I'd get the AMD FX 6100. Get that one if the Phenom isn't available.
As for graphics, a Radeon 5700 series card will max the game out.
If you want to play the upcoming GTA V, or GTA IV with any kind of reasonable framerate, the only way to go is an Intel i5.
