Hi,
I’ve an X98 Pro – I’ve been using it for about 4 months (it’s the Windows 10 only model). I have had no problems with it, and I use it for some fairly intensive applications (MS Office, Chrome, etc.), and a few games. I’ve not directly experienced the processor throttling, and I’ve checked a couple of times. It can get warm sometimes in a game or when charging, but not very. In my opinion, it’s one of the best tablets I’ve ever used – it’s fast, the SSD is good, the build quality is excellent. I love it, and use it for about 4 hours a day for various things. Battery life could be better – that’s my only gripe. I can’t speak for the Andriod firmware, though ….
