Have decided to use the i5 2500k, because of the price and because it fits easily in comparison with the i7 from the price and performance just for me. My goal was to be well prepared for the gaming the next 2-3 Jahe for my school and my hobby. Memo to self: "Done!" Did the processor in Win 7 performance index in test times and it reaches a 7.5 (out of 7.9). So I am very satisfied. My first practical test today was indeed limited to the Windows level, as it has very good-looking. With my EKL Alpenfön brings these Core nothing to sweat, cool 28 - 38 ° spread over the 4 cores. Despite much multitasking between applications I never got more than 50% Kerauslastung. The rule was rather bored at: 1 - 14%.
In summary, it is to say: + Faster processor, with the option to overclock it + Is only 8 - 10% below a comparable i7, but it costs a piece Weinger $$ + Good Price + High Quality, as I know the Intel + With the right cooler it stays cold
