You don't need high FSB for the E6600 (x9 multi), as you are probably going to reach the CPU limit before the FSB.
Normally you can get between 3.0GHZ and 3.4 with the E6600 with mild VCore increase.
That's under 380FSB. To reach 3.6GHz (9x400) without higher voltages requires a bit of luck with the CPU, Mobo and Ram.
I'm running 1.375V for 3.4GHz, to reach 3.5GHz it needs 1.45V and to run Orthos for a few minutes at 3.6GHz it needs 1.50V, not really good for 24/7 under air cooling imo.
Don't believe also on the high o/c results, most have high voltages (most people don't mention it) and are normally only SuperPi stable, not really good for 24/7 usage. For that you need dual Prime95 or Orthos running for several hours.
For an E6600 or E6400, feasible speeds are between 3.0GHz and 3.4GHz. This is what most people get without extreme measures, cooling or über expensive DDR2 sticks.
I tried both the DQ6 and P5B, it is true that the DQ6 backplate makes installing 3rd cooler a pain. The DQ6 was actually easy to set and fire, BIOS is friendly. I got same results with the P5B as with the DQ6, only the DQ6 would run Orthos longer than the P5B at the CPU limit, but it wouldn't matter as the speed was not usuable. The P5B bios is a bit more difficult to handle at first sight.
The P5B has an power down/up "fail safe" approach that turns off and on again your computer when you cold boot, restart or reset your computer. This was an issue for me, but others are OK with that.
If you want a suggestion for the moment, look into the AW9D Max or non Max version.
It has a lot of features, no backplate or power on/off issues. BIOS is very good also.
I'm quite happy with it.
The Asus P5W64 is worth a look, I'm also thinking of it.
And read a lot about the boards you are considering, check also the Anandtech forums and also

See what people are getting and what most problems are.
Just don't believe on the advice from fanboys, which will recommend you anything despite existing issues.
