I must say that ATi has a far better image quallity than nVidia cards, which is a great advantage is most cases, ATi als has the performance crown with thier great X1900XTX also man that card has lot's of sweetness in it.

a friend of mine has the X1900XT also a nice thing to have in my hands 2 weeks back , within 3 weeks I will make some nice pics of the ATi X850 XT PE AGP and the X1900XT PCI-E as combo shots
