For stability, do a 32M run. It should take you between half an hour and two hours depending on how fast your system is. Not really sure how good of a stability test it is, but some people like it.

More commonly, the 1M test is used a benchmark. Takes less than minute.

Nice PI score, but super PI for me is not the best stability tester. I have been able to do 32M Pi test at speeds that would error out pretty quick in Prime95.
Prime95 IMHO is a much better stability tester.

To give you a comparison the system in my sign does 41 seconds. You could use the search function to find the thread where a lot of people posted their scores. I know it was at least 2 pages (I think a lot more) of just 1M times.

Does a higher FSB help cut seconds off your superpi time.. or is it all about how many mhz you can get out of it?

It all helps quite a lot with SuperPI, although I've found that tight timings seem to matter more than much else. High clock speed, low mem speed and low latencies are optimal.
