It's really a bigger deal for the Intel crowd than for AMD users at this point.

Since AMD's current chips only use a 333MHz FSB, single-channel DDR333 (pc2700) RAM is enough to make full use of it, garnering a memory bandwidth of 2700 MB/s.

But with Intel's chips currently using a 533MHz FSB, and soon moving to 800MHz, eventually having dual-channel DDR400 will be able to take full advantage and have a max theoretical memory bandwidth of 6400 MB/s.

Of course that's all theoretical, and how much bandwidth you actually need is up to what you use your computer for.

And I'm not saying it's not worth it to buy an AMD mobo that supports dual-channel DDR, such as nForce2-based mobos. Just saying that's not THE reason to buy those; they bring other technological improvements that give them a performance edge, and should be the factor in deciding.

now I wonder if I got all that right?
