No the cell processor isn't more powerful, it's just that it's priorities lies elsewhere, where else a PC can run GP code and let the OS sort out shit and the processor handle itself, the Cell is harder to program for as it trades die space for pure FPU performance. Think of it as an idiot that can run 60kmph easily but won't stop if a car is heading his way. It requires more handholding, more optimization and certainly more programming time. No, even the PS3 has it's own dedicated GPU, which is a geforce 7900 Equivalent.

PROTIP : The PS3 looks good because it's games have low native resolutions and then are upscaled. And code is more streamlined on the developers part.

Some rendering is hardware limited in form, it's obvious that the 8800 series will beat the 7900 series in the PS3 in terms of qualitative rendering, no amount of fancy programming can push hardware limitations, although you can trick the end user or implement more costly forms of rendering at high perf hit levels.

If you must know, a 2k PC can beat a 2k PS3 soundly. The end.

Fun factor is still at debate, i've had alot of fun with a Wii and it has totally rubbish specs.

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~~~

Console Graphic Tech is far more higher than PC graphic setting.......
