You PSU is a little on the low side for sli, it might work but its just not got the headroom I would like. A stressed PSU is a very bad thing. You could sell the 1070 and jump up to a 1080 which is better suited for 4k

I can got to 1440p

Id rather wait for the 1080ti because the 1080 would only be a 20%boost

Well you have an FE 1070 so an non FE should be overclocked by a good 10-15%. A non FE 1080 with a good OC could be as much as 30-40% higher.

You could go 1440p 60Hz but for games like Skyrim you don't need superfast fps and 4k will look better. If you were into FPS or Racing games then I would opt for 1440p over 4k every time.
