Hi folks, got a question here. I'm looking at ordering this:
Refurbished iMac 27-inch 3.4GHz Quad-Core Intel Core i7 - Apple Store (Canada)
Now, on the refurb description page, it says that its L3 cache is 6MB. But every description I've seen of that iMac is that it has an 8MB L3 cache. When I went to Apple Live Chat and asked someone, she basically just said "it's 6MB, that's how this is configured." So is that something configurable? I thought that the L3 cache was determined by the logic board/CPU config; why would this be different than a standard 8MB cache? Or IS it only 6MB, standard, for these iMacs?
EDIT: It looks like the sites I was looking at are wrong--it seems that 6MB is indeed standard. I think the 8MB cache was the previous model, come to think of it. NVM folks, move along, nothing to see here....sorry! 
Not a huge dealbreaker or anything, but I'm curious about the discrepancy.

I'd bet it has 8MB, just a typo.

I have plenty of more important things to do, if only I could bring myself to do them....

That is the BTO i7 model of the top iMac. The BTO i7 has 8 MB of L3 cache, and the default i5 has 6 MB L3 cache.

The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.
