So TweakTown made a nice video straight from Gamescom 2011 that shows a AMD FX 8-Core Processor Black Edition running on a Asus Crosshair V Formula

GamesCom 2011 – Over at the ALTERNATE booth there were a bunch of partner products on display and one that quickly got our attention was a system demo by AMD.
 
They had a system setup running the upcoming codenamed Bulldozer eight core FX Black Edition processor on an ASUS Crosshair V Formula (AMD 990FX chipset). In the video below you get one of your first looks at a live working Bulldozer system running Dirt 3. You can see all eight cores in action too as the Windows Task Manager performance tab was open at the time.
