If it's for gaming (or even for gaming and other normal computing tasks), there is no need to drop another $100 on the hyperthreading-enabled i7-3770k or 2700k or 2600 or whatever. Just get a sandy or ivy bridge i5, which has the same per-core clock capability and the same number of cores but lacks HT. An i5-2500k, 2550k, 3570k, or the non-OC variants are all going to be just as good in gaming as the hyperthreading i7 kin.
