When you upgrade to this CPU option does apple ship these with the locked multiplier core i7-2600 or the unlocked multiplier core i7-2600k Also what are the other chips it ships with. Is the 2.7ghz core i5 the i5-2500s? It's the only 2.7ghz quad core i see. But it's a special low power version that's actually priced higher than the i5-2400 which is 3.1ghz and the next upgrade apple offers (doesn't seem like a cheaper priced chip would be an upgrade that cost extra but i5-2500s is the only SNB 2.7ghz quad core), it's before the core i7 upgrade. There is also a 3.1ghz core i5 option which im guessing is the i5-2400 since its the only 3.1ghz quad core So the 27" imac comes with these processor choices (PLEASE correct me if im wrong) Standard Cheapest Option: Core i5 2.7Ghz = i5-2500s??? Next upgrade option: Core i5 3.1Ghz = i5-2400??? Top upgrade option: Core i7 3.4Ghz = i7-2600 or i7-2600k So to sum it up. What are the exact 3 processor's used in the 27" imac?
