The one I am using now has worked pretty well for current games I have been using it on(World in Conflict, Battlefield 2142, Hellgate, Orange Box, etc.). And the lower end is going to be used for games primarily like Rise of Nations, Dune, and Command and Conquer(not 3).
On top of that fact, I don't plan on getting a higher end graphics card for the single core, if anything a 7 series Nvidia at the most.
