Probably a Voodoo3 would be ideal for that system. What type of AGP slot? Universal or 3.3v?

PII covers a 3 year period between 1997-1999; the TNT is an OK companion to a low speed PII chip like the 266 or 300 (I prefer a G200+Voodoo2 instead), but you have a 450MHz PII, and most of the games you declare interest in are 1998/99 titles. You are definitely better served with going for a card that would pair better with a late PII or early PIII CPU. Judging by your games and current card I don't think you are really interested in glide backwards compatibility so I'd say you can go for a GeForce 256 (1999) and call it a day. If it's hard to find (it seems to be) then you can just get a GeForce 2 MX 400 (2000) which should have relatively comparable. Personally, I'd go for the Voodoo 3 3000 but in this case it doesn't seem to be the best idea.

thank's for the answer ! I I've found a GeForce 256 on local forum for sale )

I think, universal. I'll look when at home)

It's of course depends on what you want to do with it and personal taste, but for any given PII / III class machine, I think Geforce 2/3/4 (any kind) is almost always a safe bet.
