Yeah, they're a great chip. But I would recommend against for gaming on a budget.

The main difference between the chips is i7's have hyperthreading. Which doesn't make any difference in games.
Not today, but after octocore Playstation 4s and Xboxes comes out, future games will probably use more cores and hyperthreading.
