Prey is the only OpenGL engine in our test suite, so let's see what happened on the Athlon64 3400+:

The X1950 PROs push their weight around at all resolutions and settings. The Prey engine is clearly more video card dependant than system dependant on the 3400+. Let's compare results to the older AthlonXP 2500+ platform:

Here we see a slightly different story. At 1024x768, the AthlonXP 2500+ was an obvious bottleneck. At 1280x1024, the bottlenecking was far less pronounced, and we see frame rates that are similar across both platforms.
