It's mirracle but cpu can still hande gpu. It was little bottlenecked when cpu was running at factory frequency but after little oc (3.4 Ghz), everything runs smoother. I can say there is balance between gpu and cpu. I was checking it in MSI afterburner, while playing Witcher 3, gpu was loaded at 100% at ultra settings. I had also opened google chrome with 8 cards or what it is, antivirus, steam and seeding torrents maybe something else. And I don't have Tri-X version of gpu (just in case you thought that I have). I was comparing my fps with internet and I had same results. I mean fps in games. But I think that there can be problem with cpu hungry games like Cities Skylines.
