Something like this is great (http://www.newegg.com/Product/Product.aspx?Item=N82E16814127667), shows very similar performance in fact to a 670, and can be overclocked well.
 
Exactly which PSU is it? All the cards listed might have problems with a cheap, no brand unit.
Also check that it has the correct PCI-E connectors, it's not a good idea to run a powerful card off molex/PCI-E adaptors, we've had several posts where the OP has done just this and damaged the adaptors/s because they were overloaded, resulting in 'card faults'.
If the PSU is of unknown qulity I'd suggest you look for a 7870 LE card and use the money saved to purchase a decent one-550W with suitable PCI-E leads will be plenty.
