CodeCreatures Pro
We'll look at the pretty CodeCreatures Pro first. Heavy use of pixel and vertex shading should tax each card. We'll be running at 1024x768x32, 1280x1024x32, and 1600x1200x32. Note that we're using a Springdale motherboard that's faster than any Canterwood we've tested.
The FX5900 Ultra does well, as expected. The surprise are the gains made by the defunct FX5800 Ultra with the newer drivers. It's looking pretty good for the FX5900U at the outset.
