TBH you would need a stronger graphics card. 4k is ok yea but 1440p (MASTER RACE) is, for me and many others, indistinguishable from 4k. So fewer pixel, less to drive and essentially the same. But that's my little reccomendation thrown in. I'm using a 980 ti @1440p, maximum settings with a fair number of visual mods. Things do drop as low as 30% at times. Avg 70fps in the world and 144hz solid in instanced areas. Soooo much more display to drive.... It'd either be eye candy concessions or a gpu upgrade. Stick with the 1080p man, I was screaming 1080p Master Race until three weeks ago After muling it over for 2 months, reasearching everything i could, three spreadsheets later, response times, torque ratios..... welll I didn't smash it into a tree but I was still unsure. But now having done it I know I made the right choice for me. But I'd advise to make no changes unless it involves a refresh rate over 75hz. A 144 display and actually hitting that in dungeons.... sweet baby jesus.
OP
Controller works as everyone said but do you have a recliner? I rolled pc gaming in a la-z-boy for years on the big screen. hard mouse pad on the wide arm rest and keyboard in lap. explore your options
