Gaming disregard the 1045T maybe 6 cores but low clock speeds compared to the quads.
960T - Can OC nicely and may unlock to 6 cores (see my sig thats a 6 core unlock on a 960T @ 4 GHz on air)
965BE - Easily OC's to 4.0GHz on air (in theory the 4 deneb cores in this can provide more grunt than 4 thuban cores in the 960T)
Basically get either the 965BE or the 960T. They are similar enough that unless you want to take a gamble on getting 6 cores just buy whichever costs less.
