I tossed in an older Matrox Parhelia in place to limp along until I figure out what to do in the future. Whatever I buy will be PCI express, and since none of my motherboards support PCI Express, I don't just get to get a video card. And of course I wouldn't just buy a motherboard that supported my existing processor, and of course my existing ram wouldn't support the speeds, say, an Athlon 64 3.2ghz would require. And of course, my Shuttle case on the one machine doesn't support a new motherboard.
Dunno wtf will happen. I'll wait and save money.
