nVidia until the ATI Radeon 9700 comes out. Tom's Hardware couldn't release the numbers, but the 9700 was "clearly superior" to the Geforce 4 Ti 4600(128 mb)
ATi, i got pissed at nVidia, tehy has there time in the sun, Now ATi WILL RULE ALL! nVidia becam too big and all, i root for the underdog,a dn now that ATi have a far superior product, im and w/ them all the way... And now I ahve a PC that can be upgraded (I have a laptop w/ an ATi rage modilitys w/ 8mb of ram), Hello R300.
I prefer nVidia for 3d performance. Got a Ti4400 now. And the drivers are very good also. However the new ATI 9700 is a beast as I heard. For 2d imagequality the ATI is better, Matrox is best. Still sticking with my nVidia for the gaming capabilities/performance though.
