I ve got a 970 and an i7 3820 and while my rig is getting pretty outdated i was able to play doom at 1080p 60 fps with most graphics options maxed.
Doom eternal 970. Tweak your pc disable some services etc. You should be able to reach 60 fps with your gpu. See the oc version. I don t think they properly optimized this for the 970 at all.
My buddy is using same gpu and and same cpu and he has no issues playing doom on 60 fps without any drops. The textures look like and i still get wild frame drops. Basically i m wondering if anyone more experienced than me in these sort of things would be able to predict if a 970 would still be good enough for doom eternal.
