My friend's Macbook Pro has (according to system info) a quad-core 2.9 GHz i7 CPU. I was happy with the speed that Handbrake encoded videos at on her Macbook. Relatively, how fast would Handbrake encoding be on her 2.9 GHz i7 versus the base iMac's 3.2 GHz i5? Since I was happy with that speed, if it would be close I see no reason to pay more for a faster processor. Sorry for the silly question; I just haven't been able to find any good benchmarks.
