The big scores come from nvidia geforce 2 and 3 cards, so use those.. 3dfx isn't that much slower but for some reason the nv cards with the right driver are a golden combination for this project. Beating the highest scores you'll probably need around a k6-3+ @660mhz or higher and an overclocked card and all the right bios tweaks and registry settings.
