...I am pretty much disappointed after waiting months for a refresh that was suppose to be a substantial upgrade over last years iMacs. I think alot of us had unwarranted expectations due to the HUGE increase in the MBP performance. Here is where I am coming from. I am an accountant so spending money were a return isn't realized is against what I believe in. Therefore, I planned to buy the base 27" version. So many times before this refresh I was tempted to buy the base 3.6ghz dual core that was available. I am still a fan of a high clock speed because it makes a difference in daily single and dual core tasks. However, I waited mainly due to most on this forum stating I would regret it and the upgraded processors were going to be substantially better. Let's compare the benchmarks: 32 bit 3.6ghz dual core (last year) - 7,000 average 2.7 quad core (sandy bridge) - 7950 64 bit 3.6ghz dual core (last year) - 7,745 2.7 quad core (sandy bridge) - 8625 Is this really a substantial jump? You take away clock speed (even though you do have turbo boost to 3.7) and add two cores and you get less than a 1,000 point increase.
