Hi all. Currently I am using the Phenom II 940 with 8 gigs memory. Can anyone estimate whether the new Opteron 4100 Quad is any faster and by how much? The 940 is at 3 GHz. The Opteron only at 2.2 GHz and it has the same total amount of cache. The application run is Sonar Studio 8.5.3 with horrendous amounts of data to be processed per unit time. Needless to say, the 940 is maxing out, creating noticeable audio distortions. I intend to build a new system with the 4100 because it looks very affordable. What I need to find out is the amount of improvement occurring when 2 CPU groups (that is a total of 8 processors on 2 dies) are used on a corresponding MSI MoBo. It's not enough to have some, say, 20% improvement becuase the next project may be even bigger. I am looking for at least 50%+. I'd go for the 6 processor/die unit, but my new software maxes out at 8 processors and I am also under budget constraints. Thanks in advance, S.
