I have a Voodoo 2 PCI 1000 and I am thinking about buying another one ($49) so I can put them in SLI mode and thus get more quality graphics; or is it better to by a Voodoo 3 PCI 2000 for $ 99. which option is better or will both render the same result?

Please advise.

Voodoo 3
It's faster, better, and it is supported by a lot of games
