I get the same warring and UT2 stops working after loading a flight. For some strange reason that only happens when MSI after burner is running in the background, I close after burner and the warning doesn't show up and UT2 works fine.

I've got two MSI 1080's gaming x a couple of days ago, so far a single gtx 1080 is way better than 2 way SLI in P3D. I wasted my money so don't waster your money and get a single gtx 1080

I've got a Haswell i7-4770k for 5 days now. At stock speed and stock fan so far. I get 30 FPS in most scenarios with NGX. The lowest FPS I get is about 23-24. GPU GTX 560 Ti. I use REX 2 (NO OverDrive), Active sky for real weather and Word Not Allowed's guide for tweaks. I fly NGX With UK2000 and Aerosoft airports. The performance is very good and very smooth(I've got some flashes because of the tweaks) . As for the temps on gaming MAX 65 (Stock Fan). I am more than happy with the Haswell system since I've upgraded from Core 2 quad q9650. This is my humble few days experience with Haswell

NHD 14 is gonna do the job pretty well. Enjoy your new build
