having radeon as the video card in my main gaming rig, i have dismissed win2k as a gaming OS. >>
Really? You might find out different checking over at
Rage3D. The much newer, and far more frequently updated beta drivers available there fix a lot of visual issues/compatabilities with games running under Windows 2000. If you also grab a tweaker such as
RadeonTweaker, you can likely squeeze more FPS out of your rig than you're likely to see on
most any review site (proportional to the CPU/memory setup of the reviewer's rig, of course

).
I have no complaints on both a Celeron/128MB RAM/Win2K Pro/(flashed & tweaked)Radeon LE, and a P2/128MB RAM/Win2K Pro/Voodoo Banshee setup at home---relative to my experiences with running the same games on those machines under Win98SE, for example. As a fellow Radeon-, and 3dfx-product user, my advice would also lay in not lending
so much credence to 3DMark scores, as it seems to have been geared toward nVidia cards.
Check out the
boards there for any further advice, or experiences.
As for the Banshee, I've noticed
VoodooFiles has some great new Win2K drivers for it (not "official"

), and the site may have something available on the driver/tweak/advice-side for you, and your V5, too. Hope any of this helps.
