The Radeon 9100 is the same as the 8500, but it's clocked
25Mhz slower than the 8500 (8500 = 275/275, 9100 = 250/250). Most of
them can be overclocked to 275/275 easily though. You mention yours is
overclocked to 275/225. Are you sure you don't actually have a Radeon
9000 which is default clocked at 250 core 200 memory.
The 8500, or 9100 is easily the better card when compared to
the older GF2 GTS. I however have a Radeon 9000 in a second machine,
Celeron 1.1Ghz, and do not see the bad performance you do. I had went
from a GF2 MX 400, and the Radeon 9000 leaves it in the dust.
How did you go about changing the drivers? Sometimes, files,
and registry entries can be left behind when you just do the
uninstall. I always run driver cleaner to make sure the previous
drivers are wiped clean from the system.<!-- ~MESSAGE_AFTER~ -->
