So my Retro PC right now has a 3DFX Voodoo 3-2000 for DOS and Win 9x gaming. It presently has a Celeron 500, but I am in the process of gutting the machine to replace the motherboard with an Intel SE440BX-2 with Pentium III 500, which also has a free AGP slot. I was thinking of running dual-GPUs to get compatibility with early 2000s stuff like Freedom Force and Silent Storm that the Voodoo just can't handle.
I have an IDE to CF adaptor, so it's pretty easy to swap out a 98 install for an XP install and back again, and the motherboard does have the option to select the active video output from either AGP or PCI. My plan right now is to get the second video card, then disable the 'wrong' video card in the device manager of either a Win 98 install (which uses the Voodoo), or a new XP install (which uses the other card). I'm guessing that Windows doesn't even care which card is the BIOS default, so I can probably leave the default on PCI for DOS gaming, and have Win XP take over the AGP if I boot to it.
I haven't picked a video card yet, but I'm thinking GeForce 2 or better on the NVidia side, or comparable Radeon.
The only thing I'm potentially worried about is power draw; does anyone have good references for old cards that I can do some power calculations?
Any thoughts or tips? Something I'm not considering? Anyone already doing this and want to share experiences?
