Intel's Core 2 Duo processors

High-Res Gaming Peformance:

In Call Of Duty 2, we saw very little difference between the spread of CPUs tested - you're going to see very small - if any - real-world gaming benefits in this title.

Performance in Quake 4 scales a little better, but then if you're applying Anti-Aliasing at this resolution, the bunch is going to tighten further.

The same is true for Half-Life 2 Episode One.
