Recently bought:
Xpert 2000 (Rage 128 VR)
Xpert 2000 Pro (Rage 128 Pro)
3Dfx Velocity 100 (basically a Voodoo3 2000 w/RAM sliced in half)
I thought I was buying a Rage 128 GL, as this is what the seller listed, and I didn't look closely enough at the photo. Oh well. I have an extra Rage 128 Pro now, and it's better than advertised. It was cheap and no sense returning it.
Quick tests of the 3 on a Wilamette P4@2.0GHz on SiS XP4 Chipset w/256MBx2 DDR SDRAM Windows ME (no patches) DirectX 7.1
No tweaking done, I just threw them in there, loaded whatever the latest drivers I had available, and let 'er rip.
