Don't have a scanner handy, but read these benchmarks in a mag;
(System; Athlon XP 3000+, 512Kb L2 cache, ASUS A7N8x motherboard, 2*256MB PC3200 RAM)
(all at 1280*1024 2*AA 0XAF - can't be bothered copying them all!)
(approx -read off of a bar graph)
UT2003
Radeon 9800 pro - 150fps*
GF 5800 Ultra - ~178fps
Radeon 9700 pro - 121fps
GF 5600 - ~97fps
Radeon 9500 Pro - 90fps
GF 5200 - 60fps
*minimal difference between this and the GF5800 at 1024 res, though
Aquanox
Radeon 9800 pro - ~63fps*
GF 5800 Ultra - 70fps
Radeon 9700 pro - ~52fps
GF 5600 - ~36fps
Radeon 9500 Pro - ~35fps
GF 5200 - ~17fps
*is the best at 1024 by a good 10 fps
3dMark 2001
Radeon 9800 pro - ~12500*
GF 5800 Ultra - ~13000
Radeon 9700 pro - 11000
GF 5600 - ~7800
Radeon 9500 Pro - ~7500
GF 5200 - 5000
*best at 1024 res
Based on these charts I be looking at, the 9800 is only best at 1024 res - the GF5800 beats or equals it at higher res. Interestingly, there's a set of Comanche benchmarks where the 9700 beats everything at select resolutions.
From PCZone magazine, incidentally. (don't actually normally buy it, just got it to get Wolfensteint:ET off the coverdisk. Not a great mag for reviews, etc , to be honest - although the HW stuff is better than PCGamers')
