Which video card is better for DX10 gaming ?Nvidia 8800 or ATi 2900?

i mean for hard core gaming ..and know saw that nvidia has GDDR3 but in ATI DDR3 whats the different ?



and whats is the best card for hardcore gaimg?|||The ATI 2900 is meant to compete with the Nvidia 8800 GTS. Its performance is still behind the 8800 GTX and Ultra. The best card for gaming right now is still the Nvidia 8800 series.|||I think XTX2900.

Some says nVidia 8800.
