Hello everyone

Im sorry if im posting this on the wrong sub-forum, but ive been searching the web for information on this all week long and havent found anything.

First of all, im Portuguese, and im searching help on international foruns since i couldnt find any support on local ones.

As a computer enthusiast (work on a computer sales store) Im building a "retro games machine" to play old games, like Carmaggedon, Tomb Raider, Need for speed 2 and so on.

Currently my basic configuration is:

Motherboard Soltek SL65KV2
Intel Celeron (Tualatin) 1.3Ghz (overclocked to 1495mhz)
1.5Gb ram (3x 512mb Sdram pc133)
2x80gb Hitachi ATA100 Drives
Microsoft Windows 98 SE with a patch for the 1.5GB of ram (W98 doesnt enjoy computers with over 1GB of ram)

And a Matrox Millenium G400 Max DualHead as main grafics card.

Well, want i want to do (and need to know if its possible) its to install a 2nd 3dfx card on this system, so i can play games with glide support.

My original ideia was to get a VooDoo5 AGP and just switch it with the Matrox everytime i wanted to, but that would probably get me some buggy crashes with the drivers unlease i did a clean installation of
windows everytime i switched them. Plus having to open the case everytime...

So that brought me to a new and more complex ideia: Both cards on the same system. Obviously I would need a PCI version of VooDoo5 (there isnt really much different in performance), or i would try 2x VooDoo2 (SLI).

My doubt is, since the matrox g400 is also a 3d card, will the SLI'ed voodoo2 work on the system?

What about any other voodoo3/4 or5? Will they work correcly as a 2nd graphic card?

And yes, I do prefer the ideia of keeping the Matrox on the system, since the G400 is clearly better than a Nvidia Tnt2 and it supports bump mapping wich i think voodoo5 doesnt (correct me if im wrong)

Any help will be trully apreciated.

Thanks!
