Which one of these builds is better for gaming?1

[xxshortbusxx]

I am looking between these three builds, trying to make the choice of spending the least amount of money while still being able to do what I want. I am going to build for basically purely gaming, I will do some web browsing, but not much. I plan to basically only play Day Z, as my old computer all of the sudden can't handle it. I would like to stay below $680 for a budget by the way... I do have a Monitor and will be trying to get Windows 7 separate from these and will just get a cheap keyboard from Walmart or something. Anyhow, which one of these builds would be the cheapest to play a game like Day Z on?

the i5 is best

i5 hands down but I'm guessing the fps difference wont go beyond 5 fps so I'd go with the I3 if you have budget issues

The i5 is the best one it faster than the i3 (well and amd too) also GTX 660 > AMD 7770. You would need to bump up to a AMD 7870 for it to be in the same league as the 660.
