Outside of Halo, Doom3 (NV worked closely with developer) and a few old OGL games, I?d say the XL800 is going to be generally a little faster in DX (90%+ of games) and the GT in OGL. This seems to bear out in those computerbase.de results Russian linked to. The XL was faster in (Farcry, UT4, TR-AOD, HL2) and the GT in (Doom3, RTCW).

X800 XL ? 4753
6800GT ? 4603
3Dmark5 used DST (depth stencil textures) for the shadows on the GT which boosts its score ~ 10%. DST isn?t even in the DX spec. (it?s arguable whether Futuremark may have wanted appease NV) but they contested that quite a few of the big name developers would be supporting DST. The vast majority of games currently don?t support DST and how much future games will is up in the air.
3Damrk5 supports PP. (which probably boosts the GT?s score somewhat). I suspect that a lot of new games will follow HL2 and not bother with PP and use DX8 for thew FX series. PP can help the new NV4x?s but they don?t really need it and PP does nothing for ATI cards.
