So i know they both have practically the same performance, one beating the other in some cases, and they'll both do the same in vr but I'm also considering maybe buying a 4k monitor and I don't know which would be the better buy. I know the 980 ti has 6gb of vram and the 1070 has 8gb but at 4k I heard it barely touches th 6gb mark. Plus on eBay I can get a 980 ti like $60 cheaper than a gtx 1070. And I know your about to say "at that res you should really be going for a gtx 1080 or 1080 ti" but I can't afford the the 1080 or the 1080 ti so I'm stuck with this. I could really used some pro help.
