Not bad, not good. I've got a 5900 that thinks its a 5950 sitting here that I need to get plugged in. Problem is, I haven't got enough +12 to push it, so I'm building a 5v-12v switching converter, since I'm not using much on the 5v bus. I could pull the 12v off my
CPU and run it on +5, but that would put a hellish load on the switching FETs at the voltage I'm running.
