This has probably been asked countless times but need an opinion from users of Sandy Bridge and Ivy Bridge. Currently have i5 2500 (unclockable) and wished I had gotten the K model. I want to upgrade to an unlocked i7 2600K or i7 3770K. Is the extra 70 dollars for the Ivy Bridge worth it? I do mostly flight sim (FSX) which says hyperthreading is used so that steers me towards the i7 but is it worth the extra 70 dollars. I use discrete graphics (6870). I know power consumption is down from 95 to 77 but cooling will not be a problem. Any opinions. I would appreciate your input because I am leaning towards the Ivy Bridge.
