Apologise that this has taken So long. But please appreciate I have been pressed for time. These results are not recorded demos. They are real world results. From in Game fraps Benchmarking. I did three runs through a set spot "I" Chose in the map. Divided the results to reduce margin of Error.
Athlon XP Barton 3200+
2.2 Ghz 400 FSB
1 Gig DDR400 (Dual Channel)
Geforce 6800 Non Ultra (325/850)
Albatron KX18D Pro II (Nforce 2 400 Ultra)
The spots I have noticed that show the most improvement is where Heavy Geometry is being rendered. Also anywhere there is grass being rendered. Grass areas have seen a performance improvement of 10-20%.
