So, I have OEM Dell motherboard of my Optiplex 7020, And I did not really find anything useful about the BIOS of the motherboard of my optiplex 7020, So how can I make sure its BIOS is up to date and optimized for gaming?
Is my motherboard capable of gaming? Does motherboard even matter?It seems the newest BIOS (version A03) for your PC was realesed in 2015:

And it is an OEM system so it is definitely NOT optimized for anything other than the minimum requirements to run your OS and a web browser.
OEMs purposely disable optimization settings in their BIOS so they don't have to deal with support issues caused by users tweaking the settings.
PS
Run CPUz and click on the Motherboard tab and look at the BIOS section to see what BIOS you currently have.
