Ok, so I was wondering how much does the higher FSB really effect anything, so I did some tests. Each set is from a E6600 at 3.0Ghz with a 8x375 and 9x333. I ran each test in the same order and gave the CPU a little bit of time to cool down in between tests. Both settings are stable 15+ hours with ORTHOS Blend.

*Note Both are actually running at 374.8 and 332.8, so the 9x multi should be under the 333FSB strap.

Idle: ~31C
Load: ~45C
CPU: E6600 with Zalman 9500 and AS5
RAM: G.Skill 800Mhz at 5-5-5-15
Motherboard: Asus P5B
PCI-E: 101Mhz
PCI: 33.33 Mhz
CPU Voltage BIOS: 1.3625
CPU Voltage Windows: 1.328
CPU Voltage Under Load: 1.280

Background programs: NOD32 and Google talk.

Looks like there's a slight gain, please comment.
 
Seems to me the only real difference is in your multitasking test; 7-1/2 % is probably real where a fraction of a % or even 1-2 % is probably within error.
 
How does gaming fit into this scenario
if the gpu's are held back a little the increase in overall fsb speed will help. as data will be moving faster but the at some point the increase in fsb speed will not help. esp if the cpu speed doesnt increase past this platue... this assumes your not running AA/AF single card or sli. i see how a higher increase would be seen in a sli/cf setup with aa/af off or low settings. since even in sli/cf with aa/af max the gpus are the bottleneck. Then that would negate any gain from the higher fsb speed.
 
If I get my new chip I will do this again.

Hopefully I will still remember :)
