My advice?
Skip Windows 8-8.1. Run by it. Don't stop, don't look back (to me, it was similar to that all-star Microsoft hit we all loved to hate - Vista - but that's just my opinion) ..
Windows 7? Yes - awesome OS - and the drivers are all there, and the HCL was totally re-written - and it rocks...
Windows 10? Absolutely terrific for me so far on all four of my workstations (two image editing, one coding and one Surface Pro 3). Takes a bit - BUT, coming from Windows 7 - is pretty easy to migrate into...
Just my $0.000002 - probably worth less...
