I'm running tests with 2 PCs from 2003 with TOP configurations.
They are stacked next to each other and run the same benchmarks and games.
- One with ATI 9800 XT (top 2003)
- One with NVIDIA FX 5950 Ultra (Top 2003 Nvidia)

in games and benchmarks in DirectX 8 : the GPUS are similar
in games and benchmarks in DirectX 9 : there is an abyss: ATI always wins and by a lot.

Nvidia was a generation behind in performance in 2003!
Do others have the same gpus? what do you think?

an example :
- if you try Call of duty 2 in DX 7 : boards both fly.
- if you try Call of duty 2 in DX 9 : nvidia switches from 70 fps to 15 fps. unusable


(obviously identical conditions: perfect pc formatted and optimized)
