Hi, I was looking for a graphics card for my first gaming build (http://pcpartpicker.com/p/ypNgrH) and was wondering the difference in performance between the Sapphire Radeon R9 280X and Asus GeForce GTX 760. The 280X is only 10 dollars more than the GTX760. Also what are the differences of the two GPUs in terms of Nvidia vs. AMD? And last, what is the difference between different brands of the same graphics card? Thanks!
