Been a great stable board. Im looking to upgrade the video card to an HDMI capable card with a GT 430 processor (having a tough time find a pci 1.0a card with hdmi support). Now, understandbly after very minimal research 1.1 is compatible with 2.0. However 1.0a from reading "may" have apparent problems. Most issues seem to point with the power requirements between 1.1 and 1.0a specs.
