Best PCIe Card For $300-$550 : None

Why spend $375 for an 8800 GTS 640 MB or Radeon 2900 XT, when the cheaper 8800 GT will soundly beat them both more often than not? And how could you justify spending $500 on an 8800 GTX for the marginal performance gain over the 8800 GT? Indeed, for the price of a single GTX, you might be able to purchase two 8800 GTs in SLI mode which would beat the 8800 GTX.

Best PCIe Card For ~$600

With the 8800 GT cannibalizing the recommendations for the rest of the GeForce 8800 and Radeon 2900 series, the lone wolf still stands: the 8800 Ultra. This is still the fastest card that money can buy, so even though the 8800 GTX might have lost a little luster, the Ultra still has the champion's title going for it. If you have unlimited funds, this is the card to get.

AGP Interface

Best AGP Card For Under $100

With identical features to its faster 7600 GT brethren, the 7600 GS lacks only the core and memory clock speeds - however, the GT's clock speeds are so high that the GS pales in comparison. Nevertheless, the 7600 GS is a good performer in this AGP segment. The worst thing we can say about it is that it's pretty close to $100, and the 2600 XT doesn't cost much more for a good deal more performance.
