My Skylake build is five years old and has been running 24/7 for 90% of that time and had some serious gaming sessions included in that time. It is still going strong.
It had all the features that I wanted and was made with rock solid components so I recon it was worth the money. At present I recon it has cost about a £1 per week and will cost even less per week the longer it keeps on going. Pretty cheap for all the entertainment and bargains I have found on the net with it.
If you look at mobo comparison test reviews you find that they nearly all run about the same even cheaper mobos will perform almost as well as the top ones. It is the quality of the components that count. The very top end mobos are getting you to pay for fancy extras and the cheaper end ones are made with lower end components that may run forever but probably will not. Somewhere in the middle is that mobo with just the features you want and will use and no extras and made with rock solid parts at a very reasonable price. The trick is recognising it, rather like finding a needle in a haystack
