On the box, the processor requirement for Call of Juarez is a Pentium 4 at 2.2 GHz. This is fairly low even by last summer's standards when the game was released in North America, making Call of Juarez the least CPU demanding of the four games we have tested.

It turns out that Call of Juarez isn't so lenient on all the GPUs we have tested: even powerful cards like the 8800 GTX have a hard time cranking out a solid 30 frames per second.

Not to ruin the surprise, but out of the four games we tested, Call of Juarez performance was by far bound the strongest to GPU performance with our E6700. Even severely underclocked, our Core 2 Duo at 1.6 GHz is very much sufficent to prevent any CPU bottlenecks -- we did not even gain half a frame per second going from 1.6 GHz to 3.0 GHz. While I expected the faster CPU speeds to not have a tremendous affect on the game,  I was surprised at how there were basically no performance gains going from the bottom of the chart to the top.
