I have Windows 8 Pro 64-bit running on an AMD e450 Foxconn NetTOP. I am about to switch my CarPC which has the previous e350 microATX soon since it's touchscreen, should be nice, hopefully it installs. Windows 7 installed fine and runs fine on the e350 but haven't checked with Windows 8 Pro yet... Will let you know as soon as I upgrade!! If you already upgraded please let us know your experience. I think I should run some benchmarks before and after 7 --> 8 transition. Know any good benchmark programs I should use?
