I am a 5K+ owner since june 2019.
I received the Artisan yesterday may 4th 2020 and I also had the 8K+ at the end of march 2020 but I resold it since.
The Artisan is not a better headset then my 5K+ for me.
If my 5K+ was a 10 out of 10 , I would say the Artisan is a 8.5 - 9 out of 10 and the 8K+ is an 8 - 8.5 out of 10.
The image is sharp on both headset. ( Equal - Same )
I found my 5K+ have better colors then the Artisan.
I also prefer the SDE pattern look on my 5K+ over the SDE with the Artisan.
To me the SDE or Pixels is a bit less visible on the 5K+ and a bit more present on the Artisan.
I also thought that the Artisan would be less GPU demanding with the lower panels resolution but it is not to my biggest surprise deception.
My PC is a Ryzen5 3600 CPU 4.25GHZ OC on all cores , Evga RTX 2080TI Black Edition also overclocked with Nvidia driver 445.75, 32GB Ram 3000MHZ.
Here are my benchmark results with Assetto Corsa with the same same settings with Pitool 255 at 120HZ with normal FOV on both headset. A back to back test and the second test with my 5K+ had a better average FPS result.
