Thanks, Matthew! That's exactly what I needed. Looks like I'll
need at least 500 watts.
I sort of figured the OS wouldn't be the issue, since I thought at the
very least the basic driver set would load even if the card wasn't
compatible. But, I've been asking and looking around, and I kept
encountering "You have to uninstall your old drivers". So, I thought
maybe there was just something I didn't understand about how video
works. My first suspicion was voltage levels, but it just seemed to me
that an AGP 8x-compatible mobo would have the proper voltage settings
for an 8x card. I wouldn't think there'd be any variation there, given
that everything started going to PCI-E right about the time it came into
being.
Still looking to see what kind of prices I can come up with on power
supplies. I have a couple of "geek-squad" type buddies (one of whom
built this system for me) to check in with and see if they may have a
good deal.
Thanks again for the link!

Good idea... here is the one that I use:

As it notes, PSU output diminishes as the capacitors age. I would
always be suspicious of an elderly power supply.
BTW, Walt, if you're not getting any video output (no BIOS messages
etc.) then you can safely rule out the operating system (Win XP) and
drivers. You're not getting to the point where they would be relevant.
