Hi, I am about to buy a GTX 980 video card and I don't know the difference between the manufactures, the prices have a dramatic change ranging between them so i'm hoping I can get an answer to what are the differences and why are there 2-3 hundred dollar increases between them? I can afford to buy any of them so it is just a matter of which one has the HIGHEST quality. I'm tempted to just buy the highest priced one and moving on but I want to know if they are just scamming me or if it is a large improvement. Thanks in advance for any new info
