Doom 3

I ran the default timedemo, 'timedemo demo 1', three times on each resolution and quality setting, and took the average of the second and third scores.  We ignored the first one as it was always much slower than the following ones as the game was caching textures off the hard drive.   

Far Cry

This is a custom demo we use in various PCP articles, run three times and average the second and third run throughs. 

The performance gains on the DFI board are much smaller in these more GPU intensive games, but the slight difference remains.  It is not a noticeable change, however.
