So I read that to use AMD's smart access memory feature on the new 6000 series, you have to have CSM in the bios disabled.If it isn't disabled, you would need to do a full reinstall of Windows 10. Most setups CSM is enabled by default, I check and mine is enabled. Can anyone confirm this, if I had to do a reinstall of Windows 10 that is a real deal breaker for me.

I believe that being able to disable CSM and booting Windows still means that your drive is formatted GPT.

Those that don't have that will need to convert their boot drive, or reinstall Windows if they don't want to bother with command line conversion.

so under normal conditions (not counting Smart Access Memory) is it best to have CSM enabled or disabled?...what benefits does having it Enabled give you?

If you need Secure Boot enabled, you’d disable CSM on an Intel board.
If your components, especially gpu, support uefi then you can disable CSM if you think mixed mode is doing something measurably problematic.
You’d want to convert mbr partitions to gpt.

If you are specifically working on Linux environments I can see wrangling with CSM to be old hat.
I didn’t know SAM on AMD required CSM to be turned off.
It’s really not a big deal, I wonder if nvidias SAM implementation will be the same.
