I have 2 pcs right now. One is the kids and has a 2560 x 1080 monitor. The graphics card recently went so I bought a replacement. The replacement is a rx 480 8 gb. In my pc I have a 290x 4 gb. I run 3 1080p monitors independently and in eyefinity + 1 1440p monitor above them. The question is which card should I use to run which setup. My understanding is that they perform similar, but will the extra v ram help the additional monitors in my pc? Should I bother swapping them out? I guess I just need to know which card I should use for which set up.
