Xbox 360) Yeah
Revolution) No...it's going to be a very decent card. Probably something like an X800, maybe a bit better. Stop exagerrating to the point of stupidity. Oh hey, looky der, you can't ban me.
PS3) Not really...the Cell processor, if it's ever released, is going to have architectural problems out the wazoo. Every new architecture does, and you never see it until mass release. If all 6 of its supposedly functioning cores even end up working towards the same purpose, and not just puttering and die out, I'll be impressed, considering how testing is going on the thing. I was excited for it, but now I'm just scared by the implication that it could kill Sony (especially with a rumored 2007 release). The GPU, however, is NOT based on the 7800--in fact, the 7800GTX in the dev kits was morbidly underpowered compared to the GPU. If by "based on" you mean "loosely tied to while melting the face of", then yes. Otherwise, you, sir, are incorrect.
