A good Gaming Pc for under $700?

I'm looking for a good gaming PC under $700, that can handle games such as, Battlefield 4, Minecraft and Black ops 2. Any suggestions?

Get an I3 with a 7850 AMD card, 4GB RaM and a 128GB SDD with a cool master 525w PSU and whatever decent chassis you can get with the left overs.

Buy an I5 if you have spare cash and you'll get better performance or upgrade the GPU to a 7950 or both.

Mine is great it was 630 before tax and it plays games great. Check it out on bestbuy.com. I don't know what it is exactly but its a lenovo with an i5 processor and a 2 gb graphics card and a terrabite ram. Look it up on bestbuy
