I am using a i5 2500K CPU. My advice is go for i7 2600K, you said its mainly for gaming and photoshop and watching movies for now. But how about in the future, you might want to to do some video encoding, rendering, and conversion from one format to another. I7 2600K is right for you. For future proofing, i7 2600K is the right choice. For gaming and hyperthreading its the best CPU choice for you.
