Ok this might seem a bit silly asking about products still fresh out of the gate and in this case not available yet. But…*

I was wondering if anyone who had some really good technical knowledge thinks it would be possible to replace the i5 proc. in the iMac with the i7 if I chose to do so down the road. This means it would be user replaceable. It seems the general consensus is that they are socketed so why not?

I ask this because to be honest I don't think I need the i7 iMac at this time but in the future (i.e. 3-5 years) I might. Therefore I could save the cash now buy the i5 iMac and later pick up a cheap or used i7 proc. And because my Apple care will have run out voiding a warranty wouldn't be an issue.

My workflow usually consists of having Lightroom, PS4, Adobe Bridge, Safari, Adium, iTunes and Rapidweaver all running at once. So I think the i5 would do a decent job of running these for now.

so what do yawl think?
 
Gots to wait for the fool to break the freshness seal and see which chips and sockets are used.

And to see if Apple is using standard PC carrier packages, especially since it isn't too big a deal for Apple to request a non-standard carrier (something they did with the Mac Pro and the MacBook Air.)
 
The Core 2 Duo 3.06 GHz models will be limited to LGA 775 based processors.

The quad core Core i5 and i7 iMacs are based off of LGA 1156. Right now the only thing that's faster is the Core i7 870. Nothing beyond that on the roadmap right now for LGA 1156.
 
When you say epoxy, do you mean Apple actually puts a goop of glue and sticks it on there?
Kind of...

Here's the Mac mini's processor.
 
You'll note that the glue stick came about (more widespread) the time of the XBox and Nvidia GPU problems... just another layer of reducing the shifting of the chip during thermal cycles.
 
Knowing Apple, I think they will epoxy and/or solder the chip.
Well it was socketed in the past and the LGA 775 based models are socketed as well.

They must have gotten a killer deal to buy into a dead socket this late in the game when they should have been using it since 2006.

Good point, I didn't even think about that. But didn't the imac g4 have a non socketed processor?

Edit: Nevermind, they were socketed... Don't know why I thought otherwise.
 
I think its been discussed here that they use different sockets set.

Not really, the i5 750 and i7 860 use the same socket 1156 and so does the i7 870. The i7 920 and above use the 1366 socket.

Too bad the processor is relatively hard to get to as the upgrade to the 860 costs almost as much as an 860 by itself.
 
So it's safe to say the revisions are a stop-gap?
LGA 775 in such expensive hardware for the lack of a better term is stupid.

I suspect the entire iMac line is going Core i# and LGA 1156(B) in the next revision for the sake of simplicity. Clarkdale is coming up at a lower platform TDP cost and BOM compared to the current LGA 775 one. With Hyperthreading (2 cores, 4 threads) in some cases you might be able to squeeze near Core 2 Quad performance.

Yeah I agree. On newegg the difference in price is only $90 between the two. Too bad Apple wants to charge $200, but I guess they need to keep their investors happy. :)
 
Lol...

Knowing Apple, it'll be a Foxconn Socket 1156 ... so extreme overclocking and going to a higher draw CPU might not be a good idea.

Which seems to be the overclockers unfriendly socket and board if they have this socket.

Note: while it is the stay away board on the PC side ... Foxconn is a rather common vendor for parts on the Apple side, and they create a lot of boards and sub-assemblies for them.
