Time for an upgrade -- advice please.

I think my mobo may be fried.... still trouble shooting but am already thinking about a potential rebuild.

Here is my current setup:
i7-4770k
Asus Z87 Deluxe
Asus GTX 1080 Strix
Corsair Vengeance 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600
Corsair H75 cooler
Samsung 1TB SSD

What the best mobo/cpu/ram combination, leaving the rest of my system intact?

I do lots of gaming and flightsim, which is CPU heavy (Prepar3d)

**If its just the motherboard then I would just replace that with a Z97**. Other then that I would go (OC) Skylake i7, Z170 MB & DDR4 RAM or (non-OC) Skylake Xeon, C236 MB & DDR4 RAM.

(Most Z97 MB's will be fine to use for OCing that i7 4770K).

I would keep the 4770K and overclock it if you haven't already. I think you would be disappointed with the performance gain of a Skylake i7 since it is only marginally faster.
