You could get a used 5770 on craigslist for 75 for sure.
If you don't mind looking at older Gen bang for buck card
try a 4870. The 5770 is more future proof and will have
more overclocking headroom. The 5770 is also a 40nm
card meaning it will consume less energy and generate
less heat. A 500w psu will be plenty!
Also the pcs+ 5770 comes factory overclocked with a better
heat sink, it is $100 brand new right now.
