Joshua, Thanks for your response.
I may be wrong but Barcelona at 2.3GHz is being offered at the same price as > Harpertown at 2.8GHz. > Yes, both opteron 2356 and Xeon E5440 are comparable in pricing (~ $700), but it is 0.5 GHz difference! I am going to run some tests, but our previous experience with 2.0GHz Barcelona was not very encouraging. > I think you can find Barcelona 2.3GHz from Dell for $1800 USD or around > that > with SDR. > Is this price with fully loaded unit (both cpu chips and decent amount of memory present)? I would like to get the link to the source of info, if available.
