Hd5450/8800gt on e4500 @2.2

I want to know if my cpu will bottleneck an hd 5450/8800gt. I got an almost 5 year old computer this one exactly http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c01154863
im choosing between those two. I know that the hd5450 isnt really a gaming gpu but it runs on less power than the 8800 and my psu is 250w. If anyone want to recommend a gpu that my cpu wont bottleneck and will run on little power plus be a semi decent gaming computer or at least better than the hd5450 that'd be great. If its under $50, it be great.

Specs
Intel Core 2 Duo e4500 @2.2
2gb (1x2) ddr2 @667
generic 250w psu

The CPU listed isn't too bad and I don't think the 8800GT will be much of a bottleneck but it does have a high power draw and it would be a little risky to try it on a 250w PSU. The HD7750 can provide good performance at a low TDP.
