the X600 is garbage compared to the 6600GT.
Also yeah megadeth it is AGP, but still PCI-E is overrated right now because it may use 'more' of the bandwidth it still doesn't use all and I haven't found an article yet that suggests PCI-E is completely dominating over AGP quite yet.
megadeth is absolutely right. the PCI-E version of the X850 is insane. i know this from experience. the 6800 ultra extreme has no chance.
You got facts to base that off of? Because if you don't then it's just words in the air.
EDIT: Here ya go, a PCI-E version article courtesy of Toms hardware. Same results.
"In terms of performance, the new ATI cards don't have much to offer. "
So yeah I still don't see why you guys think the PCI-E is 'soooo much greater' and where you have this 'experience' with it is also beyond me.
