Windows backup never really works for me, got no backup software I really know and trust. the Palit Jetstream GTX 980 is DX12 ready. I installed windows 10 on a VM worked alright a few stuff that bothered me tho what I really hate is the auto update being forced so I made it enterprise adding it to a long term branch thing that slows down the updates considerably
Votemarvel -- good suggestion re reserving (I don't have to install if I don't want to but it gives me the option for a whole while I research things)
Sapphire -- I'm with you on this one for now. My rig is only a year old and runs nicely with 8.1. The new features on Windows 10 sound like fun (ie Cortana) but I don't want to reinstall all my software (my EXPENSIVE but older software -- I'd be hooped if any of it didn't run on the new OS)
I dont think that's the case, I think you can only upgrade for free and after one year you wont be able to do so nor you'll have a licence key for a "standalone" copy.
