I think this is pretty good value taking into account the AMD Quad Core 3.6. The graphics card is good enough I guess although I personally prefer nVidia. However 1g DDR3 graphics seems good. I would increase the ram to 16g if you can manage it as it's a desktop. I recently bought a gaming laptop from simply acer, a 5552g with ATI6740 graphics 512mb, AMD quad core 2.10 and it plays L4D and Medal of Honour w/o any probs. Hope that helps.
