Hmm Cat7 seems like overkill and a waste of money.
Also, NO most devices don't use 10gbs speed. Your computer, Router, and Console is most likely rated for 1Gbs. A 10gbs nic alone costs between 300$ - 500$. Unless your going to be doing some heavy data transfer or streaming hd video to something like a plex server you will probably never be using the max speed of 1Gbs. Also in order to handle that network traffic you are gonna need one hell of an expensive industrial router.
Save some money. The monoprice cat6 utp will work just fine.
most routers bought within the last year can do cat7 speeds 1GBPS
100mbps is for the dummies
Cat7 is rated for 10Gbs I believe
Also you dont need shielded cable.
If you don't mind me asking how much did you pay for Cat7 cables?
