I've purchased a Flex 3 AMD based laptop last year, as a way to try and avoid screen tearing issues I had with Intel hardware. Ever since work stopped on the legacy driver, the Intel modesetting driver works ok but offers no option for "TearFree" option, which is an issue with certain compositors like XFWM4 used in XFCE.
The laptop itself is decent, though the keyboard is not great. Linux compatibility is ok, though there are some hoops to jump through and it is unfortunately the case with the CPU itself (AMD 3020e, also known as RAVEN2).
