If you are open to other gpu,psu models, it would be better if you state your budget and purpose.
People can suggest better alternatives for you here.

@ Op - tell us your budget .. anyway, at the price of GT640 + you can get a HD6770 or add ~1k more - you can get a HD7770 and yes, the PSu will be enough.
