I am building a system, that will be used to host 2 minecraft servers, a website, and to play minecraft of course . My problem is, do I want to get a 6 core Sandy Bridge Processor and Have 12 threads running at 3.5 GHz (intel core i7 3930k) or Do I go with a smaller Ivy Bridge and get only 4 cores (8 threads) running at 3.9 GHz (intel core i7 3770k).
