Motherboard question - FSB ratings.

I was looking around and pricing some computer parts for a new system, and while picking out a mother board, I noticed that for similar CPU type and chipsets, different motherboard manufacturers had different FSB speeds. The Gigabyte board I had planned on buying (last 3 systems used Gigabyte MBs and I've been happy with them) FSB rating is 800, where as a Asus one was listed as FSB2000. These are both boards for a 939 pin Athlon 64FX.

Guess I've been ignorant this entire time, didnt' realize you could have different speeds for the same processor. How much of a performance difference does the difference make? Also, I've been hearing alot of talk about the NForce chipset. Does it offer a performance boost versus VIA? I think the Asus uses the Nforce3 Ultra chipset. How are they as MB manufacturer?

It's just different terminology

For example, the actual FREQUENCY of Intel's FSB is actually 200 MHz. However, they dump 4 packets of info per clock pulse, so it's counted as 800 MHz FSB.

AMD did the same thing, basically.

So there is no advantage to 2000 vs 800? I mean 10 packets of info at the same time is better than 4 no?
