May be you are talking about i5 series. It's the 32nm, less power series. Less powerful than i7.
Becos, i7 uses triple channel memory while i5 uses dual channel.
Go for i7 instead of just waiting for new processors to come for rescue.
Those 2 components are WAY overpriced if you're concerned at all with value. Go for the i7 920 and the P6T Deluxe V2 for a MUCH better value for your money. I built a whole i7 PC with brand name parts from scratch and didn't even spend as much as that 965 processor ALONE costs.
