soni7007 is on a distinguished road
I am planning to buy a workstation with the fastest processor available. Currently, i have a Xeon 5160. I am confused between the two : AMD Opteron 2389 and Xeon W5580 (that's Nehalem, right?).
Also, is Opteron faster than Xeon 5160?

Any suggestions, ideas, benchmarkings available?

Thanks in advance!

Hi there

There is good information in the benchmarks from Fluent (Ansys). See
http://www.fluent.com/software/fluent/fl6bench/new.htm

It looks as if the Nehalem is much faster than Shanghai. I would not go for a Xeon 5160.
Your final choice must evaluate total system cost (especially RAM).

good luck
