I second that Corsair PSU. I actually have the exact same unit and love it. Quiet and reliable.

Between the HD 6770 and GTX 550 Ti, I'd go for the 550. Better performance than the 6770.

Best solution

The are so similar in performance HD6770 is faster than a std clocked 550Ti but most of the 550Ti's on the market are overclocked and therefore faster than HD6770. I can not choose between them basically only on price!
Either should fit fine in your mobo!
