Which of these processors is better for chess?

[Paul Bedrey]

Q6600 (8MB L2 cache,2.4GHz,1066FSB)
Q6600 (6MB L2, 2.66GHz, 1333FSB)

Both are Quads. Obviously the higher GHz is preferred but can anyone provide me with a layman's explanation as to how L2 cache and FSB come into play?

Recently I bought a Quad and expected it to whip my dual but the Core 2 Duo more than held its own even though the GHz was the same. I can't figure out if I screwed up in purchasing my quad or its just randomness or there is more to a strong chess computer than GHz. Here are the specs for my machines:

Q6600 @ 2.40GHz 2 GB memory 64 bit OS
Core 2 Duo @ 2.40GHz 2 GB memory 32 bit OS

Why isn't my Quad cleaning the Dual's clock? Both are the same speed and have the same memory and to top it off the Quad has the 64 bit OS? I'm confused.

What does this mean? What program? what was the depth difference in match play?

2 gig memory will leave small hash for quad in match play.

here is my quad results. big difference in time to solve and double kns.
One of the differences is I have 4 gig ram with 1024 hash in this test using XP Pro 64. Check your task manager to verify 4 threads running
What programs do you have? what is your kns in this position?
