Heh, good point
Eh, what ports? They have identical IO from what I saw
Which one? (I like the Krait better because of the color scheme but it's up to you of course)
I'd get the z97, you don't save a ton (maybe $50 at the extreme). Although, the 4790k would be the best CPU you could get, which isn't a huge improvement over the 4770 (unless you overclock the 4790k)
