What motherboard do you have now?
I personally prefer ASRock X99 motherboards, use them, switched from Extreme6 to WS, because Extreme6 have only 3 PCI_E slots
Extreme series ASRock are nice motherboards, although they don't have OC Socket and therefore you can't OC cache
Other motherboards, hard to say, owned two Asus Rampage V Extreme, first one killed 5930k and second one killed 5960x, both with older BIOS currently they're in friends PC and no issues as we are used new BIOS and we are put all manual voltages where AUTO has been
Gigabyte not sure if I would touch, have bad experience from X58 era and X79 and their RMA is pain
Hope this helps
