Thanks for explaining, I was unaware of the AMD's advancements. My
background is mostly as an OS Engineer - system administrator, systems
architect - tailoring the OS to meet company standards, setting standards
and policies.

Now a days, I have left that field and go to the dark side - security - so
not much techie stuff hands on.

Your explanation made sense and made me look up stuff. :) thank you.

Too bad, i could not make it into the meet yesterday, had to do a chocolate
and tiny gift bag stuffer for my son's school valentines day. Hopefully,
next month.
