Ok, since you have a standard compaq PC, I'm pretty sure you'll need a new PSU (power supply unit), if you want to use a 9600XT.

I just hope that your Compaq's case can fit a normal ATX PSU. If you want to cut costs as much as possible, and get a quality PSU,

i think Single GTX 295 or two GTX 285 is better for you
