I haven't been in the pc building business to long. Only got into it when NVidia Maxwell came out.
I'm building a used system for a friend. Should I get:

I7 2600K and 2 HD 6970's in crossfire(£340)
or
I7 4770k and gtx 760 (£400)

Both are for complete systems with other components being very similar, so which one is the best value. I don't care about power consumption or heat output and no fanboyism please ;-)
