So im putting together a new rig and I want to have it speced so I can run a 3440x1440 monitor setup well. I am wondering what level of GPU i will need to run my games at 60fps, also im wondering if my CPU will have any bearing on how well I can run games on that high res of a monitor. I have a GTX 1070 already and would like to keep using it but im not sure if that is realistic. I am also concerned with futureproofing, how long can I continue to run modern games at that res. The games I plan on running are as follows. Fallout 4, Mass Effect Andromeda, GTAV, For Honor, Star Citizen, Ghost Recon Wildlands, and other games like that. Mostly open world RPG's and action games.
