I've since unplugged my 8800GTX, put in an old Radeon7000-PCI card and noticed the noise when OCing. Also, when I start to run Orthos the noise intensity picks up and get incredibly more noticeable (at either stock or higher).
I've got a SeaSonic S12 650W PSU, and I didn't have this problem with either an M32N-SLI or Striker mobo.
So is my board bad?
This evening I'm going to swap my PSU and try my old 600W PSU and see if anything changes.... although I doubt it will.
Thanks!
