I have some duplicates in my collection of video cards so I threw them on eBay. They would be pretty good cards for a DOS game comp.

Matrox Millenium II PCI 4MB WRAM
Diamond Stealth II S220 PCI 4MB SGRAM (Verite V2100)
Diamond Stealth 3D 2000 PCI 4MB EDO RAM (S3 ViRGE 325)
Generic S3 Savage 4 AGP 32MB SDRAM

The Verite is brand new. OEM packaging I believe. I bought them as a 3 pack off eBay a month ago or so. It's not even opened. The one I did open was flashed to the latest BIOS already which clocks it at V2200 levels.

The Millenium II I used for a little while in a retro comp. It's quite fast in Windows and runs TIE Fighter SVGA nicely.

The ViRGE is pretty decent in Windows too. I didn't try gaming on it, but since it's a S3 it should be fairly well supported for DOS games.

I picked up the Savage 4 at a local computer shop since I'd never messed around with a Savage 4 before. A friend of mine recently handed over to me a Diamond Stealth Savage 4 so I figured I'd try to get rid of this one. It works as well as any Savage 4, but it's not clocked as high as the higher profile cards. Nice little passively cooled bugger though. Works well even in XP.
