Try downloading Geforce Experience if you haven't already. that is a good way to stay up to date and get beta drivers if you want. PC's are varied and problems are not the same across the board for everyone... Luckily Fermi still new enough to get continued support into directx 12.
Most of the biggest problems with Windows 10 have been fixed already. And those that haven't will be eventually. Windows 10 is still very new. Wait a few months on windows 10 before upgrading for the bugs to be worked out... Nvidia wont let them stand or they will loose business.
If you want any kind of statement go to a support forum. I myself am waiting on why my 970 somehow doesn't meet requirements to record using game DVR with windows 10. Just need to wait a bit for the bugs to work out.
there was an expectation that Nvidia to be dragged down by china and Erope woes. Nvidia has now shown that the crazy drop we have seen is completely unjustified. I still think we should not be trading below 25.
