However, it would be nice to know how much your power supply can put out. If it's too small, neither of those are going to work unless you upgrade. Your current one may be ok though. What is your computer's model?
Also, if you want a cheaper card, there's the 4670. This one has a lifetime warranty, is $80, and has benchmark scores that are about 10% better than the one lhuser posted. Also requires less power.
edit: Vinman has the right idea...that ati card is great. The nvidia one has the same specs as lhuser's, but is cheaper...about right for that card. You can still get better for the price. That PSU is ok as well.
