Sapphire Pure Platinum A75

The Nexuiz graphics performance is the same between the Sapphire and Gigabyte motherboards, as would largely be expected.

The Gigabyte A75M-UD2H was slightly faster with Lightsmark, but that is not too demanding for the proprietary Linux graphics drivers and the difference was nominal when the frame-rate is already 160+. For those more interested in Fusion Linux graphics tests, see this recent Phoronix article.
