Is B150 viable to use in a gaming PC. I'm not planning on doing anything crazy. Just a decent GPU, CPU, and few hard drives. I won't be doing any overclocking. I want to make sure there aren't any major handicaps vs the Z170 for my purposes.
If you aren't overclocking or doing SLI B150 is fine. For most gamers these boards provide more connections and expand-ability than they will ever use. Really, USB C is nothing more than a gimmick for the average gamer. How many are going to be connecting an external SSD or RAID array? There isn't much else which will saturate USB 3.0 at the gamer or prosumer level necessitating 3.1.
For most there is just going to be a video card, monitor, keyboard, mouse, internal hard drive, optical drive (they will never use), RAM, Speakers/headset, USB backup drive and Ethernet/WiFi connected. Some will opt for a 2.5 SSD fewer will go M.2 or drop the hard drive altogether. Some may buy other controllers.
Having tons of devices connected internally and externally is a lost art. I remember my computers in the late 80s and early 90s. Loaded with expansion cards and external devices.
Overall this would be a good board for most gamers. My only real grievance is no TOSLINK. I prefer using a fiber optic connection to my surround sound. I don't really see the point in six analog audio connectors. Either use a two channel analog connection or use a proper digital connection if you want surround sound. A bunch of analog connections for surround sound is a waste. The source material is digital so you can either go with a pure digital connection or have a loss in quality as it is converted from digital to analog to digital. Of course there always is at least one analog conversion as speakers are not digital.
