How low a power supply can I get away with running my x1950 xt with
The manufacturers recomendation is 450 w
I will have a e4300 hopefully overclocked along with a 320gb sata hd

Check how many amps the psu can deliver on 12V. If it's about 26 or more then you'll be fine.

I'm running a 430W TruePower 2 PSU with an X1900XT, overclocked Athlon X2, two hard drives, two optical drives and so on, so you'll either be OK or right on the edge of stability. I'd try it out first and swap it later if you see any weird stability issues that you can't trace back to anything else.
