For real, nice system there duder. The only upgrade I've made in the past few years was a 7800GS which plays all the games I'm interested in real Nice on moderate settings. I am somewhat envious of your system and can imagine how great the graphics must look with such games as Crysis and Farcry2. My son has a dual core, PCI express Nvidia 8800GT, 4Gigs of Memory and I've seen some amazing graphics on that so I can imagine what your getting.
