2011 27" iMac w/ 3770 upgrade?

[Djerzprod]

I was wondering if anyone has tried this yet? I figured it should work since the TDP on the 3770 is 77W (which is lower than the 95W for the 2600-2700). If the lower TDP won't allow the 3770 can someone please explain why?

I spent the past week searching for some kind of answer and all I can see is that people would rather wait for the 2012 iMac (spending unnecessary amounts of money when the 2011 can still be, potentially, spec'd out to the hilt.

Thanks for reading.

Works, i tried it on my stock cheapest i5 27" (the one with 6750M). I discovered that Apple uses the same logic board for the stock i5 model and i7 CTO while dissembling my iMac for the first time to add SSD. The i5 uses 65W TDP where as the i7 uses 95W TDP. The i7 3770 uses 77W TDP. Few things to note:

1. Intel HD 3000 is gone and Intel HD 4000 don't work (no big deal, I'm on the AMD GFX all the time)

2. About this Mac will show "Processor: Unknown 3.5GHz Quad Core"

Thank You hackerwayne! This is the information that I needed. This is the best news I've heard in a while. No more need to wait for the 2012-2013 iMac. I think retina is a gimmick anyway (no need to wait several more months for that). All i care about is performance, and this is great news! I really hope that others will be able to use this information.

Keep in mind that the nx gen of iMac might come with higher end graphics card like the Nvidia 6xx or 7xx series or AMD 7xxx series. That can be upgraded but most probably gonna cost more then the i7 itself . My iMac warranty expired, thats why I'm doing this.

hackerwayne,

good job on your upgrade. Could you give us an idea of the performance? I created a thread on iMac benchmarks on this a while ago:
