Hi I cant figure out which GPU to use. So far I picked out a Evga gtx 960 ssc 4gb but im still doing research on which gtx 960 to get or if I should get a r9 280x. This is my first time building a pc so I dont know much about it. Here is my part list: https://pcpartpicker.com/parts/partlist/
If you are going to get 4GB version of the 960 it will not worth the price. So for around 200$ better option would be r9 380 since it will outperform the 960 in almost all aspects.
Between the 380 models I would personal pick the Sapphire nitro model > gigabyte g1 > msi.
And for these cards a good 550W PSU would be more than enough:
