Hi, I've read all the threads on the i7 vs. i5, and have a pretty good understanding of them (i5 is enough for a majority of users, i7 is useful for Handbrake or heavy PhotoShop usage) I am ordering a machine with the Fusion Drive, best video card and additional RAM. I am willing to pay the additional $200 for a slight performance increase and possibly slightly better "future-proofing." (I tend to keep a machine for a very long time) In reading online, I've come across several negative comments about the i7: - Possibly causing problems with some games (I will be gaming on my iMac) - Possibly running slower than the i5 in certain situations - Running hotter than the i5 (Although it sounds to me that Apple has done a remarkable job on the cooling systems of the new iMacs) All of these negative comments seemed to be of the "I've heard from someone..." and not direct experience. Are any of these arguments based in reality? If so, I will go with the i5. Otherwise, I would like to get the fastest possible CPU and go with the i7. Thanks!
