Hi! Sorry, yet another questions about CPUs. This is the very last one. I'm debating whether going for the i5 or the i7 iMac 27'' model. How often do you people with the highest CPU model iMacs (i7) experience the fans rev up? Are the fastest i7 CPU iMacs in general more noisy than their lower clocked i5 counterparts? I guess the most relevant comparison would be the last iMac 27'' models. My new iMac purchase is going to be really expensive, so I want to get it right. I'm debating going for the 3.4ghz i7 (over the 3.2ghz i5), but if it's at the expense of a more noisy computer with noises going off at moderate loads, I'd just rather go for the i5 (for my use hyperthreading is more about futureproofing). Again, I would greatly appreciate anyone who has experience i5 vs i7 iMacs, if there's a difference in general temperature and fan noise with moderate-high loads. (Windows 7 and gaming + OSX in general) Thanks!
