I have an Intel Xeon W3550 with 12 GB of RAM and a GTX 1050 2GB. Should I upgrade my CPU or GPU? I am looking at putting in a GTX 1060 3GB as reviews say it is way better than a 1050, but I also do not want to have a bad bottle neck with my CPU. I do realize upgrading my CPU will require a new motherboard. My PSU is 550 watts so I am not too worried there. I play games like Battlefield 1, GTA V.
