How big can I go?

I am looking to build my first PC, but am running into some issues with my current system. I think my GPU may be the cause and am wondering if I can upgrade it now, and then build the rest later. But, I'm afraid that my Dell PSU may not be "big" enough to handle a higher GPU (you know how pre-fabs don't leave my room for upgrade). I'd prefer to not make my new build now (financial woes), but I also don't want to get a smaller upgrade to fix my current problem.

My current PSU is:
Dell model # L375P-00, 375W output

Ignoring all other considerations (which I know is hard to do)...what is the best ("biggest") GPU that I can get that will run with my current PSU?

ATI 5770 or Nvidia GTS 450. either one is fine for gaming @ 1680 x 1050 or less resolution

Go ahead and buy a Thermaltake psu, I have one that 450w dual rail and it really good.

yeah , its a solid 375w unit that peaks around 425-450w. It powered ATI 4850 with no issue out the door from DELL and that card uses more power then either the GTS 450 or ATI 5770. Both those cards under stress with an over clocked i7, total system power is around 250w.

avoid the thermaltake and coolermaster, they sell crap PSU at under 600w. sign of a noob talking out of their ass when they recommend them.
