Don't think, know.
For more detailed information try lshw, which is probably in the repos of whatever distro you're using.
If you can't see anything on screen when the PC boots, wait until you're sure it's booted then try pressing ctrl-alt-f1. That might give you a console login.
I can appreciate if you don't want to spend money on the machine but it might be worth seeing if you can scrounge a newer video card from somewhere, or buy one cheap second hand.
