From this list of coolers, which would you recommend for the 5500?  And how would I know if they have compatible mounting holes?

Planning to build a retro system with Win98.  Can I install 2 video cards, one geforce 6800 agp, and one 3dfx 5500 pci on Win98?

Is it possible to use a Voodoo3/4/5 as a secondary board as you would for a Voodoo2?

I don't even remember what kind of hardware existed during 3dfx times.  So whats the most recent CPU/motherboard/ram I can use with Voodoo cards?  I current run a i7 920 with Win7 64bit and WinXP 32bit.  I have a spare PCI slot open, can I just stick a Voodoo card there?  I know WinXP driver exists for V3/4/5, but are the any Win7(64bit) drivers available?  Also are there Win7(64bit) drivers for V2?
