Vc branch ready for testing

[JL VT]

I have overclockable memory but I'm fairly sure we are not bottlenecked by
memory, nowadays nearly nothing is.

But I can still test, I can test at 1333 mhz and 1866 mhz (just an example)
and see if there is a chance. Is there any other way to check for a memory
bottleneck?
