First of all, the question was "is a v3 3000 better than a tnt2 m64", not "is a v3 3000 better than a GF2, Radeon or V5".
The V3 is far better than an m64, especially in games.
The v3 is very trouble-free, and will work with any configuration.
3dfx regularly releases drivers.
2d quality is awesome, especially at high res.
I get 65-70 fps in Q3 at 800x600 SHQ, and 45-50 at 1024x768, perfectly playable.
Glide is great in EA games like Live 2000, it looks MUCH better than D3D.
The V3 can be had for about $100 new, or $60 or so used, a great price.
I have yet to find a game that is not playable at 1024x768, and 800x600 absolutely flies.
True, it isn't the best-looking, but it's good enough, and the speed makes up for it.
On a side note, I used to own a GF DDR, and it was great for about 2-3 minutes, when is when it usually froze. BIOS upgrades, mobo drivers, AGP 1x, etc did nothing to fix the problem. I put in a V3 and haven't had a crash/freeze in 3 months.
By the way, anyone that buys games to look at the sky is pretty queer.
