Which one is the best deal? does the spec justifly the price difference? Thanks!

First one would perform better, mainly because of the 680 and the 3770k.

EDIT: Why playing at 1366x768?

Such overkill for 1366x768, the 3rd build would max everything no problem.

Best option would be

3570k

Decent cooler

8GB ram

GTX 670 4GB

This ^^

I would have a look for a better build more suitable for you as none of them have what you actually need, also would be worth saving some money to get a nice 1080p monitor by the sounds of it, really no point in getting a 670 or 680 to game at such low resolution......................
