I was curious, what is the speed for different types of connections (AGP, PCI, USB, ect...). I realize there are different mutlipiers that make the maximum higher, such as AGP 8x. Just looking for the base speeds. Everytime I put it in Google, it thinks I am talking about internet speed.

What I am looking to do is compare the different types of connections so that I can optimize my current computer to prevent a bottleneck. I am not sure if it is slowing down on the RAM, HD, internet connection or even CPU. Granted, it is fast, just looking to optimize it.

You can find all of the different types at http://www.computerhope.com/help/bus.htm along with lots of other useful information related to these technologies.
