What speed DDR2 should i get?

[50bmg]

I plan on buying a new mobo in the spring, but i need RAM now. My current mobo is 3 yrs old. It specs say that is 800Mhz bus and it supports 667Mhz DDR2. The specs were written before 800Mhz RAM was out. With me going to a new board soon can i install 800Mhz ram in my current mobo? I don't want to spend $150 now just to spend another $150 in the spring for my new mobo.

I want to go with 2x2G PC-6400(800Mhz). That will give me 2 slots left for growing. I want Vista 64 on the new pc in the spring.

My current board will support up to 4G. So, that is ok, i am not sure about the 800Mhz. Will it hurt anything or even run? I see others talking about buying higher speeds and slowing them down to get better timing. Is this similar?

Thanks

Yes, the RAM is usually able to run at lower speeds. But, it depends on the brand, part, etc.
