Which procesor is better for a desktop Intel Core i7-2600K / 2600????
For Performance & reliability go with 2600k, for budget and mainstream use go with I5 -2500k it is best for gaming, Media editing and it has same integrated graphics same as I7-2600.
So go with 2600k or 2500k nothing else is unsatisfactory.
Ps. Overall performance and worth of cost is 2600k go with it.
