You have very good powersupply.It can handle upto hd 7950 or gtx 670 easily along with your rig.

I would consider gtx 760 @$ 250 - really bang for buck or at higher price - hd 7970 ghz

You can run any of these cards with this PSU.
I estimate your system to draw no more than 150W in peak (probably around 110-120W during normal load). Without GPU.
This gives about 10-12A on +12V rail (obviously not entirely true, as some load comes from 5V rail).
Your PSU has 40A on +12V rail. In pessimistic scenario this leaves you 38A available...

GTX 670 uses approx. 13A, 660ti 11-12A.

Right now the best bang for the buck would be GTX760. Slighlty slower than GTX670, but much cheaper.
