I was planning on getting the 2600k since it is sandy bridge and I keep reading that ivy bridge runs hotter (will most likely oc so it is important) although it takes a bit more power I think sandy bridge would be right for me with a COOLER MASTER Hyper 212+ still need to find a mobo though
It runs hotter at the same clock speed, but it's faster architecture... so the ivy bridge can be at, say, 4.4 GHz, competing with sandy bridge at 4.7 or 4.8.
Even when overclocking, ivy is the way to go. (I mean, think about it. Why would Intel roll out a new gen of chips that were slower than the old gen?)
