look at the friggin benchmarks, they tell all. if the 6800gs beat the x850xt pe, it sure as hell beat the x800xl. memory does not make much of a diff, unless your playing doom 3, but thats the only game that can utilize all that much memory.
Yea screw the refurbished card.... 151 dollars for a 512 card?? BS. SOmething BAD happened to that thing.....
My x800GTO is better than or equal to a 6800GS and if you get the x800GTO2 then you can unlock it to 16 pipelines, which has a great advantage. Make sure and get a newer x800 though, maybe even an x800XTPE or w/e it is with the PE in it.
