Don't bother getting the 2700k just raise the multiplier to 27 with the 2600k.
Go for the Hyper 612, bigger brighter better then evo.
If you are going to be doing lots of video editing then you can justify upping the Ram to 16g?
Personally I'd wait before buying the 7000 series at least until June. (I call it the 6 month rule, sorts out any problems, better drivers and cards usually become cheaper)
