Gaming

If your Internet speeds are good, I've been blown away by GeForce Now on fiber.

No noticable lag and it looks great other than occasional buffering artifacts every few hours.

$20/mo for when I'm playing games that aren't on a system I have is pretty slick when the rig is good enough to max everything out.

I don't know that I'll ever be investing into my own gaming PC again given the way it ends up as a depreciating asset.

$2k upfront for a rig that's going to get long in the tooth within a few years versus $2k spread over eight and a half years with hardware refreshes every GPU generation is just hard to justify the former for.

I don't think it'd be for everyone as it's very web speed dependent, but if you have the connection to support it I've been rather impressed.
