Hi guys!
I just want to know, which video card is the better choice for me.
So should I buy a GTX 970 (one of the cheapest version in my country is the msi GAMING version) or go for the GTX 1060 and spend 40 bucks more? (msi gtx1060 armor is the cheapest nowadays)
The main question is that will the plus performance and the plus 2GB (ok, let's say 2,5GB because of the GTX 970 issue) of VRAM worth that 40 dollars?
(I didn't want to mention the amd's cards cause I wanted the R9 390 before, but it requires bigger power supply [mine is an EVGA SuperNova 550 GS] and the rx 480's custom cards will cost the same as 1060s, and I don't want to buy a reference rx 480 because of loudness and temperatures)
I really appreciate any help you can provide :)
