At exorbitant prices though, a dual PPro board *with* 2 180/256 chips, uw scsi, intel 10/100 net and sb sound can bve had for ~$320. Those chips aren't exactly fast, but you can move up to 200/512 if you like and clock them at 233. Of course the xeon will whup its ass, but it doesn't come close on price/performance. Anyway the original question I asked was how such a system would compare to a dual PII 300. > > Yes, but benchmarks at tomshardware.com have already established > > that the 100Mhz memory bus offers little improvement over the 66Mhz [snip] > Tom benchmarks Windows stuff.

If x is faster than y under NT it should hold for FreeBSD. Niall -- Niall Smart.
