I just reluctantly gave up my voodoo3 3000, now I have a voodoo 4500. Yes its way slower than a geforce and 3dfx is out of business, but it plays everygame I have with no problems.
I have owned several geforce cards and I had problems with several programs (even stuff like laplink). Everything runs on the voodoo just fine. When there is a game that I really want to play and the voodoo cannot handle it, then I will break down and get a geforce or a radeon.
