Just wanting peoples thoughts on the 2.4GHz vs 2.5GHz MBP 17" late 2011.. I am retiring my early 2011MBP 17" 2.2GHZ & want to stay with the old school 17" format.. From what i read the late 2011 was a very minor upgrade & performance boost with the GPU going to a Radeon 6770M & the processor a few points up from my 2.2GHz..Core i7 (I7-2720QM) Question is will i really notice any difference between the 2.4 & the 2.5GHz CPUs in the Late 2011 MBps 17"? I see they're both Intel Core i7 with the 2.4 being (I7-2760QM) & the 2.5 a (I7-2860QM) I will be adding 16GB of Ram & an SSD & as i use it predominately for audio (Pro Tools) every ounce of CPU power is helpful..but price-wise I'd be looking at shelling out an extra $500 for the 2.5GHz both New with Apple warranty.. Is it Crazy to spend that much extra on 0.1GHz extra CPU ? or are the I7-2860QM 's a much better processor? Any advice or thoughts regarding squeezing extra power out of these things much appreciated..
