I have just upgraded to a Voodoo 3 PCI and I have the exact same setup, it totally rips. I'm very impressed by the high resolution and the speeds I can achieve with this older computer. Hexen II, Quake II, Half-Life all totally shred and I get really decent FPS running @ 1024X768, and it looks great. I have even been running Direct X games and those are totally ripping it up too. By the way, if anyone is looking for a freaking difficult game to master, System Shock II is crazy.
NEVER: tell a boardroom full of Australian's, "I'll be rootin' for ya!"
