I'm looking to upgrade my GPU from a 960 to a 1070- problem is I have a server computer with a Xeon e3 1220 v3 and research suggests I'll get some bottleneck- but I'm not sure how much. Similar questions have been asked but with a slightly better Xeon that supports hyperthreading and the answer has been a little- so I'm guessing mine will be more. Is it worth getting a 1070 then? Or do I need a better CPU? All I want out of it is 60hz 1440p max settings- which I could still get with some bottleneck as PC gamer's review said an average of 77.4 fps @ 1440p @ max settings on AAA titles. What's your opinion?
