Currently Nvidia has the edge with its 8800 series in performance and DX10, unless you don't want to spend £200 or more - then it's more complicated.
Before that, the X1XXXs were probably the better cards out there. They had similar if not superior performance, but also could do HDR + AA
Before that, the Nvidia 6800s were probably better than the X8XXX as they had HDR.
Before that, you had the ATI 9700 pro - one of the outstanding cards in recent times.
Further back you have the original Geforce / Geforce 2's - in those days Nvidia ruled.
Maybe ATI will respond to the 8800 with a superior card - who knows.
The thing is to evaluate all alternatives when you buy and get the best features + performance for your budget at that time.
