Actually I disagree with you guys on the 9800Pro claim, the Benchmarks I have seen from some sites, show that the 6600GT are quite an impressive amount over the 9800Pro, from ATI. Now I will be upfront to being an Nvidia supporter, but I come at this with an unbiased eye.
Quote "In DOOM 3 we were able to run the GeForce 6600GT AGP in High Quality mode, which enables 8XAF at 1280x1024. As you can see in the graph, the framerate did drop below 30FPS, but it was only briefly and only down to 27FPS which was still very playable. Overall, the average framerate was 54FPS. We tested several intense levels and found this setting to be the best overall. With the Radeon 9800Pro we did have Catalyst A.I. set to its default level, but we had to set the game to Medium Quality which does not have AF enabled. We had to run at 1024x768 in order to get playable performance in DOOM 3 on the 9800Pro compared to 1280x1024 on the 6600GT.
No doubt about it, the NVIDIA GeForce 6600GT gives superior DOOM 3 performance over the aging ATI Radeon 9800Pro. "

The above address is where the quote is from.
Above all I knw about the Euro exchange rate, and I say go for the gusto man, if its only a 50Euro difference * and I know how expensive it can be in Europe. I lived in Paris France for a little while* I say go for it while the price is as low as it is, because if Demand and Supply rules apply, the price might possibly go up.
