Yep i think too it's more easy for GTX for get better score yet... again we have no soft for control speedfan on the card and like allways, an ATI need the voltage increased for core memory ( like with X1900XTX, we need increase the voltage with ATI-tool=.. like i have say my Oc on GPU is ablsoutely not maxxed... i wait waterblocks, and a better PSU... so don't make too much loud about.. i m really far of the score have been made by other peoples yet..
There's one thing in 3D06, the GT1 is yet really for Nvidia, it's funny see how even with all 3 otehr GT score under what i have, the GT1 is for Nvidia...
Wait a little bit for see what happend with 2900, new drivers, etc.. the architecture of the 2900 is really complex and need some little optimisation.. anyway i have see the XTX will come in middle of June... when i can, i switch for Cfire system with XTX..
