Advice on Graphics Cards

[Shura]

Advising anyone to buy a discontinued card is honestly quite nearsighted. It does not save them money on the long run, and the performance they'll get will be sub-par anyway.

The OP specifically said he/she was looking for a "cheap" GPU to run the game decently and if possible he/she would rather not upgrade the PSU. Hence the 6670, both 660 and 5770 require a new PSU. If the OP does decide to change PSU, then there are still better bang for buck options, assuming the OP still wants a cheap solution. Considering the OPs specs and the fact he/she runs at 1024 x 768, a 660 for $210+ is really not the best option.

If OP wants to future proof and is willing to spend extra, then i too would personally be recommending different stuff but to assume were being nearsighted simply because we were trying to meet OPs requirements only shows your own lack of comprehension on the issue.
