Seeking site that benchmarks cards using same system?

[imported_Gelfling]

I am looking for a site that benchmarks cards, but consistently uses the same "base system" such as MB, processor, ram, etc.

I currently own a Asus A7n8x with Athlon 2400+ with 1g PC 4000 and aa radeon 9800 NP (which is moded to semi-pro).

I picked up 2 raptors (36 GB verions) and long story short, they did not play nicely with the a7n8x. I figired that I would upgrade my whole system since I have the cash, but I am torn between getting a decent nforce3 ultra vs nf4. If I go the latter, it will cost an extra $100 for the MB and I will need to get a new PCI-e video card ~$200 more).

I guess I would like to see how much better the something like a 6600 or 6800 would perform vs the radeon I presently own. I know that its not fair to compare AGP and PCI-x, so that might limit me in my quest. However, I figure I could compare my radeon to a AGP 6600 or something along those lines.

Thanks in advance.

There are a number of sites (including digit-life and THG) that have done extensive roundup testing of several generations of cards on one platform. I would try a search.

As a very rough estimate, a 6600GT is about 30% faster than a 9800Pro. A 6800NU is slightly faster than that (moreso at high res with AA/AF). There is no performance difference between AGP and PCIe (it's not PCI-X; that's completely different and unrelated to video cards).
