Motherboard and OC'ing

I am lookly at a highend gaming build with i6700 CPU, Titan X Pascal 12GB and Hydolux Pro Exotic LC CPU and GPU. My question relates to the motherboard. I have read many negative customer reviews at other sites of the Asus mobo's in terms of BIOS updates, drivers, hardware failures, etc. Should I stay away from ASUS mobo entirely and ask DS to source another one instead such as MSI? If Asus is the best option, should I buy the Maximus Extreme or Hero for a highly overclocked CPU. I plan to have DS perform the 4.8 GHz OC so do not think I will use most of the Extreme's OC features and I plan to use the DS thermal control fan for the RGB lighting so am not sure how much redundancy there is there around temp. monitoring etc. Other than the loss of Wifi are there any other reasons not to go with the Hero? Mainly worried that the Hero is not as stable as the Extreme and that it will prematurely fail.

Also, I would like to OC the Titan X. Will DS perform a robust OC when I select that option or will I need to further tweak the GPU OC?

Lastly, I plan to use the Samsung 512GB 950 PCI NVMe for my boot drive and games storage. And I plan to use a 1 TB 850 EVO SSD for my additional storage needs. Should I buy the 2X option and put it in RAID or just back up to an external HDD which is what I currently do on my iMac? Storage is mainly used for photos, home movies, music, etc. If I setup RAID can I at a later date take it out of RAID and repurpose the second SSD for additional storage or will I always be locked into a RAID configuration on the two SSD's?

Thanks for the help.

Thanks for the help. I plan to use an Ultrawide for now, but I want the ability to go with a 4K monitor when the higher frequency ones come out. Sounds like I may to be too aggressive using a 4.8 GHz OC. I think I will just select the 4.4 option instead.
