Ah, the V2. The greatest product 3dfx ever put out in my opinion. What memories.
Anyway, SLI should work perfectly fine under Win2k/WinXP (for Glide or OpenGL via miniGL only) and there's several unofficial drivers you can choose from, although I prefer the last set of betas that 3dfx put out just prior to going under. I used to run a set all the way up to the time I got my GeForce3. I agree that there isn't a single Glide wrapper out there that comes close to the real thing. Seeing as I don't play Diablo II any more (the last really great Glide supported game), I've finally retired my trusty old CLV2 12mb SLI (used for OVER THREE YEARS straight!).
