Even at this high resolution, the effect of the processor's performance was noticeable in Left 4 Dead. With everything else equal, the D0 stepping was faster than the C0 stepping by 2-5%.

At the lower resolution of 1280 x 1024, we expected the processor's performance to became more of a factor (as the impact of the graphics card is reduced). However, the D0 stepping's performance advantage over the C0 stepping was limited to just 2-3%.
