    I was looking at the prices for RAM upgrades on Crucial and I noticed that they offer 2 choices:

    DDR2 PC2-6400 (800Mhz) or DDR2 PC2-5300 (667Mhz)

    Apple just offer RAM speeds off 667Mhz, is there going to be much of a difference if I choose to upgrade?

    No. The new iMac is built on the Santa Rosa platform, and Santa Rosa only supports DDR2-533 and DDR2-667. If you install 800MHz memory, it will be underclocked to 667, like mad jew says.

    Thanks for the info. So what chipset do we have to wait for, to take advantage off 800Mhz RAM?

    Unless you plan on overclocking (which I highly doubt), there wouldn't be much difference between the two.

    If you look at today's prices, you can get 4GB of PC2-5300 for the price of 2GB of PC2-6400.
