Thanks. That is a shame for me because I usually find NVidia perform better although they haven't embraced DX12 - neither have any games I play.
Again though, you understand with freesync/gsync, that you will be unable to tell the difference right? Whether you have 45 vs, 55 fps, Nvidia, AMD, etc. it won't matter.
All you will see is smooth gaming...
For me, it has nothing to do with what vendor I like. I dislike Nvidia and AMD both. There is no reason for me to like them. They are NOT my friends.
But freesync is cheaper, and like many video reviewers have stated, when it comes down to getting a GPU+Monitor, Freesync+AMD has more options and is cheaper, so it's a pretty easy choice if you're getting a new monitor and a new card in the near future, which many people will. This is of course, assuming you don't care about branding at all, and you only care about actually gaming.
The other concern with Gsync is, with so few monitors, and so little support, Nvidia may one day drop support all together for Gsync and go with the open Freesync standard. They may just give up on the whole Gsync thing as quite frankly, the benefit of Nvidia selling people the Gsync module may not be worth it, if people decide to go Freesync+AMD because it's cheaper.
That's a worst case scenario though and I honestly expect Gsync to work with new cards, even if Nvidia abandons utilizing the Gsync module and goes with the open standard (They'll just brand it differently to avoid using freesync and say the monitor suports freesync+Gsync or something).
Once you throw in other concerns beyond smooth gaming, the whole thing changes entirely.
