Wel i built the same set up for my bro, 4870 x 2 and core i7, it plays crysis maxed at around 40 FPS, and games like deadspace at constant 60. though its running vista 64 bit
perhapes its windows xp, i know xp has never been great for multi threading and thats what the i7 is all about and also its not gonna make the most of the GPU
