Processor and RAM rating VS FBS

I am wanting to upgrade a friends computer with spare parts I have but have a couple questions.  
 Would I get a better performance out of a E6600 (2.4 GHZ with 1066 FBS) than a dual core (1.8GHz with a 800 FBS)  if the mother board only supports a FBS of 800.  Basically what happens if you run a processor at a lower FBS than it is rated for.  Same question for memory, how does it affect performance if I run ddr2 800 memory when the motherboard only supports ddr2 667.  By doing this I would be able to upgrade the RAM from 1GB to 2 GB.

The motherboard and CPU FSB speeds must match. In addition, the CPU must be supported by motherboard BIOS. So you are limited to 800 MHz CPUs that BIOS supports. BIOS upgrades may provide additional CPU support.

800MHz memory should work in a 667MHz bus. Some motherboards and chipsets are "ticky" about memory so installing and testing is the only sure way to tell.

More than likely if the motherboard only supports an 800mhz fsb then an Intel core 2 cpu wont work. As willcomp said the memory may work, but if you mix it with the ddr2 667 that could also cause problems. If you post the make and model of the motherboard/system I can provide more detailed information on what it supports.

It is a ECS 945 GCT-M motherboard.  The more I reseach this the more confused I get because it is in a Gateway GT5481E desktop computer.  Even on Gateways site their specs say it wont support a core 2 duo processor even though it came with an E2160 1.8 GHz dual core processor.  I am thinking that I may just need to update the bios from the manufacters website and get rid of the gateway loaded bios and it may support a fsb of 1066.  Also will probable update all the chipset software from intel.  I dont think the Gateway specs are accurate for this motherboard.

The e2160 isn't a Core 2 Duo it's a Pentium Dual Core(not to be confused with Pentium D). According to ECS the board does support The core 2 Duo. Good chance the cpu support has been limited by Gateways bios. Just a warning if you flash it there is a possibility of bricking the board. Here's a link to ECS's specs for the board

I also have a Pentium 4 640 Prescott 3.2GHz processor.  I think I would get a little bump in performance over the E2160 with that one and even Gateway says the board is compatible with this processor.  It also has a fbs of only 800.  Any thoughts.

Actually the E2160 is faster than the P4 640. Here's a cpu comparision chart includes the E2160 and P4-640 along with many others.
