^ That completely depends on the frequency of the two chips. SB is about 15 percent faster clock for clock than socket 1366.
Yes, and I'm assuming that the average 2500k can go to 4.6GHz while the average 960 could go to 4.1GHz, so that is a 12% improvement in clock speeds.
1.12 * 1.15 = 1.29, hence approx. 1/3 faster.
Of course his mileage may differ depending on the exact chips that he gets.
