Is DDR3200 (400mhz) useful on a 266FSB Processors?

I just ordered a nforce2 mobo and 512mbs of DDR3200 RAM. I'm about to buy a AMD processor also but the Barton w/ FSB333 is so much more expensive than the fastest Thoroughbred B processor w/ FSB266. My question is, do I need a processor with a FSB of 333mhz to capitalize on the faster speeds of my DDR3200 RAM? If I buy a Thoroughbred B proessor, would I not get the maximum speeds from my memory?

Thanks

yeah, you're right....in fact even the 333MHz FSB under-utilizes the RAM.
wait for the new 200MHz FSB chips to come out or overclock a T-Bred B chip to 200MHz

Which NF2 board? Some are better@hitting 200fsb than others regardless of the chipset revision and the right board will let you drop the multiplier and up the FSB to 200mhz without physically modding it to run synchronous with that chip even near default clockspeed if you don't want to overclock the CPU much. Something to consider and I know there's the whole "that's too much bandwidth the Athlon is saturated with less" argument but in the real world I see a positive difference with mine@408DDR synchronous as oppossed to 333DDR synchronous and not just in benchmarking.

I have an EPOX 8RDA (not +), and I used an ASUS A7N8X Delux in a friends system.

<U>How stable are these boards at 400mhz FSB, given the following:
</U>1) CPU mult lowered, to run at close to stock speed
2) Memory would be Crucial or Mushkin PC-3200
