4770K and "Processing Threads"

[Fish]

Hello,

I just upgraded to a 4770k last night (from a 2500k). I'm curious what the best setting is for the "Processing Threads" setting in Dxtory. Technically this CPU has 8 threads. How many should I have Dxtory use?

I played around with settings a bit. Setting it to "2" seems to give me a very minimal framerate hit, while playing CPU-intensive games.
