Well the most powerful card that you've chosen is the 8800GT.But i'm not sure if they are $50 or not.But to answer your question,yes they will work with your current PC.To be more in your budget range the 5570 is probably the best.When your looking for GPU's just be sure to get a card that's PCI-Express 2.0 and not 2.1.
The 8000GT by a mile, or more like 100 miles! The 5450 and 4550 are not usefully faster than your very old 8500gt. You really should be looking to spend more if you want to do any kind of gaming (like $70 for a 5670) but if you can get a working 8800GT for around $50 then go for it.
