Yup,I have.It's a Samsung SM951 256GB M.2 PCI-e 3.0 x 4 NVMe running on an MSI Z170A PC MATE mainboard. I believe it's important to have the x4 interface on the mainboard to get the full benefit of the drive.
Some speeds(obviously using test software,so not real-world performance),but it gives you an idea.
Sequential write 784 MByte/sec Sequential read 1701 MByte/sec
For a comparison,one of my WD blacks...
Sequential write 113 MByte/sec Sequential read 122 Mbyte/sec
My Crucial 256GB MX100 SSD has a read speed of around 515 MByte/sec
In the real world,boot time is under 10 seconds,I think I did time it once at 7 seconds (Win 10).
I don't keep all my games on it,just the ones I play regularly or the ones I want to cut out long loading times.
If sitting around twiddling your thumbs waiting for things to load isn't your thing,then you will benefit from one.
