I would like to see the motherboard that you will pair with the 2600.
I think that the i7 2600 will still play most modern games without any issues.
Personally, I have a 6700K and am going to upgrade to a 6850K after switching out motherboard, but this comes from the fact that I enjoy over the top and expensive tech, your opinions may vary. Lol, I have like no money. I spend it all on my setup.
