Hes not wrong, max 8 GPU is what windows officially supports at the driver level for each unique driver. So 8 GPU's that can run off of AMD drivers, and 8 GPU's that can run off of Nvidia drivers. If there was a third co, we could add 8 more, but the max is still 8.
you are
WRONG too

I tried to run 10 amd cards under windows and worked fine

do you have any experience building rigs ? modding bioses ( modding , not just changing mem staps) , modding mobo bioses )
or just reading articles about what possible and what not

its really pita to set up , not a real plug and play solution

Show us pics then, of 10 AMD cards mining under windows, if you have achieved it. If you dont have pics, then stfu and crawl back to your hole of ignorance.
when using 8 or more gpu rigs, do you split psus? Lets say I've 8 Rx 480, But my psu has only 6 gpu connectors. Each cable has two gpu plugs but one of plugs is 6pin. How do you handle this?
Yes but you can use 2 +750w which is alot cheaper than one big monster psu. They is if you run 8 RX470 4g
Yeah ... good luck running 8 GPU's on one motherboard.

be patient my friend, dont be mad or angry just bc you dont know , dont understand something

your time will come ... few more months and you will see the light again ... just like you saw the lights after 6 months about how 8 gpu can work with one mobo

Another post without any proof of any of your claims, or without any substance. You really dont have anything better to do, do you?
well ... well ...
look what just happening .... ppl with a little bit more knowledge than you have , starting to discovering the possibility of windows 10 and 8+ GPU's

... as i mentioned to you earlier, of course its take some time ... for some ppl a little bit longer ( for you maybe a year ) ... for some ppl who know what and how to do a little bit sooner
