Intel i7 3770k for 200 bucks or a intel i5 4690k? Some have told me that an i7 3770k would not be worth it(even for 200 bucks) since its the old generation and a that a motherboard (socket 1155) will be alot more expensive than a i5 + motherboard. Is this true?

(My friend sells a brand new i7 for 200 bucks.)
