I'm wondering if it is possible to run my Voodoo2 12MB with a Cirrus Logic 5446 PCI
and then also run a GeForce FX 5900XT

giving me 3 displays...the Voodoo2/5446 combo would be display 3
and the 5900XT would handle displays 1 and 2

and i could play Glide games (or any game for that matter, that the Voodoo2 can handle) on the 3rd display

would this work?
and if so
what drivers do i need as far as the 3dfx card is concerned

yes,it should work.check here for some general info (setup,drivers,etc)..
