DDR3 - Thought I had this worked out

[stoofa]

OK, I thought I had the DDR3 requirements all sorted out in my head - instead I think I've just managed to confuse myself.
Right....
Taking the 3 most popular DDR3 speeds:

1066 - So this is for 133MHz memory clock, 533MHz FSB
1333 - So this is for 166MHz memory clock, 667MHz FSB
1600 - So this is for 200MHz memory clock, 800MHz FSB

So assuming a Core 2 Duo CPU with a FSB of 1333MHz.
This is still actually a quad pumped 333MHz FSB (If I remember correctly).
So for stock speeds, 1333MHz DDR3 would be required (333MHz FSB x2).

So assuming a Core 2 Duo CPU with a FSB of 1600Mhz,
This is still actually a quad pumped 400MHz FSB (Remembering...).
So for stock speeds, 1600MHz DDR3 would be required.

Now this looks fine on paper, however I believe this is actually all wrong and I'm using maths for DDR2 and not DDR3 which is worked out differently.
Could somebody just confirm for me at stock speeds:

CPU FSB 1066Mhz = ???? DDR3
CPU FSB 1333MHz = ???? DDR3
CPU FSB 1600MHz = ???? DDR3

Thanks.

Basically I'm thinking thus:

At the back-end of the year we will be seeing new CPUs/Chipsets from Intel.
These will be based on DDR3.
At the moment I'm already in the wonderful world of DDR3, but as I cascade my old machine down to my wife I will need to make more purchases.

So when the new Intel CPUs make an appearance at the end of the year we'll be looking at FSB or 1333 or 1600.
If I want to run at a 1:1 memory ratio I would need DDR3-1333 or DDR-1600 memory.
If I owned DDR3-1333 memory and had a CPU with a FSB of 1600 I'm assuming I'd simply have to run the memory at a lower ratio.
