A "bus" is just a pathway for information to flow (PCI & AGP are other kinds of buses). The hypertransport bus is how an AMD CPU communicates with the memory and other parts on the motherboard.
The HT bus (link) is very fast! Since the HT link is used to carry data for just about everything on the board, it must have a good signal at all times. When you overclock anything the signal can degrade, this is why we add more voltage to stabilise things.
When you overclock your CPU your also overclocking the HT link and this causes instability. So if you lower the base speed of the HT link you can overclock the CPU more. The CPU link to HT is independent, so changing the HT multi from 5x to 4x doesn't effect the CPU speed.
So when running 5x your max is normally 230MHz. You should always try to keep the HT link between ~850 & ~1GHz for best performance.
I'm running my link at 1300MHz (260x5) btw

I haven't tested if it gives more peformance though, but I have tested it stable upto ~280x5 (1400)
I'd say it would only help with 3Dmark.......no real world performance!
