those console graphic 50% depents GC 50% is depents on CD...dun forget xbox 360 is using HD-DVD!...HD-DVD is 50% more clear than DVD....Even Xbox 360 is using Nvidia7900XT as GC...result out also same as 8800GTS.....WHen i play Ghost Recon Advance Warfighter...in Xbox graphic = PC Very high setting (PC i used 8800GTS SLI result = same graphic to Xbox 360 HD-DVD result)
PS3...DO it got GC..i tell u it dun have.....WHY PS3 graphic so so Pretty?

PS3 using 8 Extreme Processor (Normal PC is 5Ghz super max OC with nitrogen liquid) But PS3 Processor is 20GHZ=2Trilion per second speed without OC MEANS 8X20 GHZ = 160GHZ PROCESSOR in PS3!!!!! plus using Blue-Ray Disk...150% more clear view than DVD....PS3 no GC but result same to 8800Ultra Triple SLI result (Do u guys see Grand Tusimo newest one? play games like see a Movie...SO SO  real....Even 8800ultra triple SLi also cannot do that maybe.......
Back to X-box 360....it using HD-DVD and x-box processor is 1 trilion per second speed...means 10Ghz Processor without OC....so PC how to beat those console ? Console no need GC at all using it processor power can make ur games see very nice and Very Fast!!!

DO u see Console games make u lag before? LOL!!!!
Conclusion:Console gaming they no depents on GC they used quality on HD-DVD or Blue Ray Disk to win PC......and Processor too~~~
