Agreed. The fsb tends to be the bottleneck in the main bus. However, fsp speeds advance with clock speeds.Zero Hour said:

My point being, there is a sweet spot with RAM where you are likely to have an outdated system before you have to upgrade. 2GB tends to be the spot this generation.
If you ever feel the need to upgrade to 4GB, I'd wait a few years, until you can get it for the price of 2 today.
