I was trying to figure out why you'd want to drop that sort of cash on either of those cards, which are -- let's face it -- significantly behind the current tech curve. But the common factor looks to be the interface, namely, PCI.
Am I correct in assuming your machine can't support PCIExpress (the current standard)?
If that's the case... I would go with the Nvidia. It's likely to significantly outperform the ATI board, and that's not even counting the fact that it has 4x the memory of the ATI. It's simply a better card, with better stats. The closest equivalent to the 9400 GT, from ATI, would be the Radeon 3650 HD... and even that simply doesn't match up.
For that generation of cards, Nvidia really cleaned ATIs clock. Nowadays the gap is much narrower, but you're talking PCIe for that.
