    Hi,

    I decided to go for the 3.4ghz i7 CPU after all, the iMac I'm ordering (27'' top model with 768gb) is already crazy expensive, so why not go for broke. :D
    However, my only concern is heat. It's very hard to find any concrete information about the added heat that follows with hyperthreading. The only places where I find people discussing and testing hyperthreading and temperature is on overclocking and gaming forum.
    I'm not too sure what CPU model Apple uses, but the CPUs I've read about are the 3570k and the 3770k, which I assume are the closest (if not identical) to what Apple are using in the iMac.

    Have anyone researched hyperthreading and i7 CPUs vs. i5? Is there much of a difference? I would prefer to have a cool and silent running system, esp. since I'm planning to game quite a bit in Windows 7.
    I would appreciate greatly some informed opinions. :)

    Thanks!

    from my experience with windows PCs, temperature should be 8-10% higher with HT on full load. no need to worry

    My MBP is an i7, hyperthreading doesn't give it any thermal issues. It should be ok.

    Thanks! Is this w/overclocking or stock speeds?

    stock speed. not a fan of overclocking! but as i said before ist just when the cores are under heavy load but i doubt you will be heaving any trouble. imo the new large fan design will handle the heat just fine

    Auch, 10% extra heat is quite a bit if your doing high-end gaming in Windows with your iMac. Hmm.. Thanks again!

    i don't think games are really using hyperthreading so there won't be much head increase
