12pipelines clocked faster and with 256MB's of faster memory on the X800GTO is Well worth the extra $54
And this card will be 50% faster!!!
Plus the core overclocks from 400Mhz Default to 500min-630max
Memory also goes from 1000Mhz to around 1100min-1200max
Thats a hell of allot better then the 325Mhz on the N6800XT and once you overclock the X800GTO it will be around 90% faster. at the level of a X850XT!!! or 6800Ultra!!!
N6800XT is 8 Pixel pipelines with 4 vertex processing engines at 325Mhz it will Overclock to 400max
X800GTO has 12 Pixel pipelines with 6 vertex processing engines at 400Mhz overclocks to 550min-630max
Ive got mine to 625Mhz with a VGA Silencer 5 on it.

with stock cooling you should get to around 500 to 570Mhz
