I'm noticing mother board manufacturers started marketing an Isolated PCB as a feature as if this is something new. I have news for all of you ITS NOT, not even close
This is right from msi's website today
Here is an old AM3 (Not AM3+) mother board DDR3
Here is a 775 board DDR2
and here is a board so old it has an AGP
The only board I could find that didn't have an isolated PCB was this mini itx 775 board
(sorry for the blurry pictures, its hard to snap a pic while holding a motherboard up to a light)
I write this because ALL mother boards have this feature and its confusing the audience of computer hardware enthusiasts.
