We have bought several 650's and they are xeon-based. My 2600 server platform is also xeon-based.

Any idea how a 2 GHz MP would compare to >a 3 GHz Xeon? I have run it on a 4-way 2ghz box. It is faster than my dual 2.8, but then it is _way_ more expensive as well as the 2ghz xeons (MP certified) only come in 2mb L2 cache versions and each CPU is selling for $4K or so. Makes the machine _very_ expensive. > >Regards, >Keith
