How do I remove 3dfx drivers from my system?

[nitrousninja]

I want to try out the Radeon 64MB DDR and I don't want any conflicts with my V5500AGP drivers so how do I go about removing them completely? I'm getting it a Best Buy and want to check out the difference in image quality and game performance versus my V5500. I can always take it back if I dont like it for 14 days so why not? I've heard everyone say their piece but I want to see for myself. Thanks in advance!
