this will be enough lol but for real, I wouldnt buy a desktop now days. You can get an Asus ROG laptop like G751 (I've a G751JT my self)

This is what I would buy with 1.3k http://www.amazon.com/G752VL-DH71-Gaming-Discrete-GeForce-Titanium/dp/B01578ZNQA/ref=sr_1_3?s=pc&ie=UTF8&qid=1454140713&sr=1-3&keywords=Asus+g752

edit: sidenote I did not click the link because its shortened too.. good luck with that.
