Thanks yea their is some OC potential, however I am not so interested. I can pretty much run every possible game at max settings, over 3000 by 2000 resolution (can't remember the exact resolution)(and with Anti-aliasing disabled) with the current configuration without OC.
Thanks for sharing, Its quite an amazing machine you got there. I don't think there is much you can improve except maybe if you opt for the 7th generation i7 and go 4K. Pretty sure the Haswell CPU will get you going for a long time till you decided to up the mobo and cpu.
