the specs should be affordable ..not like a addict gamers system.. it should be affordable..the cpu should be capable to handle hi res games without problem with all maxed out or atleast at high settings..not an amd processor
Look at the benchmarks with respect to the GPU first, as maximizing your FPS at that resolution will depend a lot more on the GPU that the CPU. If a single HD6970 or single GTX570 is not sufficient, then you're looking at multiple GPUs. A pair of HD6870s will easily beat the HD6970: http://www.anandtech.com/bench/Product/301?vs=292 and not cost too much more. If they do, then you'll need to lower the CPU to make budget. You can get a Core-i3 and plan on an upgrade, or go AMD with a 970BE (a 955BE may nor may not OC enough) on a 900-chipset board so you can upgrade to Bulldozer, although you may not need to.
