the PNY 5900 ultra is a 256 mb card (8 x AGP)
the ATI 9000 pro is a 128 mb card (4 x AGP)

The PNY geforce 5900 ultra is much better than the ATI 9000 pro.

allso the better video card has the faster processor and the more RAM, faster Front Buss speed, so it ain't even fair.

And the PNY came with overclocking software that I have't felt the need to use.

Don't get me wrong, the ATI was a freebie... it works fine with (some) settings turned (slightly) down.
I got it because the previous owner was dissatisfied with the performance. (Halo 3) I think it was.
