I get 13'500+ in 3dmark '03 and ca.5'800 in '05...
Seems a bit high...
A friend has same setup, but an slightly oc'ed FX55 and DFI nforce4 ultra
with 1,5-2-2-5 timings. I dont remember further specs like htt, V, etc...
and he gets 12'000 in '03... (pci express version of x850xt of course)

Whats the average performance with a similar system like mine?
