With regard to the PSU/GPU freezing issue, if you let us know the specifications of your current hardware I'm sure quite a few people around here will be able to help you out.
Might save you from having to get a new PSU if the problem lies somewhere else.
If you have the money to spend, an ITX gaming PC or gaming laptop would offer performance far superior to the Xbox One S.
Gaming laptops have a lot more longevity now, as you're able to get a desktop-class Pascal GPU and a decent processor in the mid-to-high range models.
Or, if you want to grab a console, it may be a good idea to wait for the PlayStation Neo, which will also be far more powerful than the Xbox One S.
