What kind of computer should I get?

I want one quick enough to play games on, typically bf4, tf2, and steam games. But I don't want to spend too much. If you guys could include pricing in your answer that would be great. I used to use my laptop but if course that didn't work so well.

Get a windows computer like Lenovo, Toshiba, Samsung, ASUS, Sony.

Lenovo, Toshiba, Sony are not really expensive, but good.
you can get i7 Processor 8GB about $1200 to $1500. It depends

Apple macbook is over priced, 13 inch with i5 processor and 4GB (cheapest) is already $1300

If you want to buy a professional gaming computer, check out Alienware

What is your budget? I need that in order to be able to make a recommendation.

Go for something with at least a quad-core Intel processor, 8 GB of RAM and a dedicated video card. That will cost from $800 up.
