iam not a big overclocker.how much defference does it make from stock to 4.3 ghz in gaming.orelse i would go with 2300/2400 they perform same as 2500k in most the reviews plus they can get turbo boost 400 ghz
even if there 3-5 fps i will go with 2500k.most of the times i will playing on max settings with everything turn on(maxx AA,AF @ 1920#1080),so every little fps does matter to me
