Stop the senseless arguing.
If you have any Voodoo-based card, then you should use Glide for any games possible. If you can't, MiniGL can let you play OpenGL games, and you can play any Direct3D game. The latest games that support glide, that I can remember, are Unreal Tournament and Deus Ex. Both are excellent games...
If you are planning on buying a V5, good for you! Good luck, I'm sure it'll work excellently. 3dfx always made good drivers for their cards. They were always stable, they were always reliable, they were always fast.
If you have extra cash though, a newer video card will almost definitely be better. But regardless of that, you should be careful of your purchase. Always make sure you buy something that is well supported, or you WILL be dissapointed, not a question about that. Some cards have excellent technical specifications and lots of potential, but get bashed by people and just never really reach their potential, because the ones writing drivers are lazy or don't write drivers well enough. For example, my friend's Stealth III S540 that I'm using. Great potential to be a good card. It's absolutely utterly horrible in almost every way imaginable. If my Banshee was AGP I'd choose it over the S540 in a second. Yet the S540 should technically blow the Banshee out of the water many times over.
You should be ok with most nVidia cards these days though, since they seem to have became one of the top-dogs. Good luck, in any case.
