Here are your options:

Corsair CX600
SeaSonic S12II 520
SeaSonic G 550
XFX Pro Series 550W
Antec High Current Gamer 620M
Corsair TX650 V2
SeaSonic S12II 620
XFX Core Edition 650

Suitable for normal overclocks and 600W+ units can even handle 2 GTX 660ti (though they may not have enough PCIe connectors)

It depends really. If you don't see yourself going SLI in the short term, 500-550W is enough (and even for higher end cards like the GTX680 or HD7970). The best performing unit in the list above is the SeaSonic G550 but it's a little bit expensive for a 550W unit but quite reasonable considering it's 80+ Gold efficiency, semi-modular interface, tight voltage regulation and great ripple suppression. If you have the money, I can wholeheartedly recommend it. If you'd like to save a couple bucks, the XFX 550W or SeaSonic 520 or Corsair CX600 are good options as well
