I'd wait for C3 IMO.
The 965 isn't a particularly amazing deal compared to the i5 750 (don't even say the f-word, I have THREE Phenom II systems running here as well), so I would recommend the 955 C3 or even one of the tri-cores for gaming.
The Phenom II/790FX or even 770T platforms are SUPERB, some of the best ever IMO.
They also are a better bet if you want to do a budget crossfire setup, as the 16x/16x lanes are superior to most 1156/P55 intel boards. I don't personally like dual card, so I went with i5 for my main gaming rig because of the amazing power management.
