Well, my computer got completely roasted after i installed Win10 and tried playing ffxiv on it. The nivida graphics driver went completely insane and it is still prone to black out at least eight times daily.. (It's a stationary pc from 2009 and a HP computer to boot however, so i'm not entirely surprised)
If other people with well endowed computers can handle it though then i'm sure you're good to go! but if you're sitting by a computer with a bunch of years on it's back i wouldn't recommend it.
