I'm building a new rig ...

I already have a 3.2 P4, Asus P4c800 -E Delux that I will be running with water cooling and Swifttech MCW5000-PT. I am completely torn as what type of memory will give me the best performance. I could buy 3200/3500 memory and get some good timings or go with 3700/4000/4200 and get very high fsb. Am I right in saying to an extent having better timings is better than a huge fsb?

I am considering either (Kingston, corsair, or ocz) and would like to get a few opinions as to what ram (brand and model) would give me the best performance with my setup.
