Hi!
I've decided to go for an 27'' iMac, after several years of using MBPs. However, I'm not sure what is the best choice for me is CPU-wise, the 3.2ghz i5 or the 3.4ghz i7 option.
iMac usage: Internet browsing, iTunes, Sibelius/music composing, gaming, office etc.
As I understand it the i7 is a hotter CPU because of hyperthreading, and could result in a hotter iMac with more fan noise (I'm also going for the Geforce 680MX graphics card). Is there a difference in power consumption between these two CPUs, and could I expect a noticeable difference in temperatures? (Because of the internal HD and the graphics card I would like to have as little CPU heat as possible.)
I've also heard that i7 CPUs can cause stuttering in some games because of the hyperthreading function. Is it easy to disable hyperthreading on your iMac and Mountain Lion OSX?
Thanks! (Getting excited about buying my first iMac, but it's a lot money so I want to get this right.. )
