Dual CPU 6 core with Cubase 6

I am planning to replace my Xeon 4-core workstation with a dual-Xeon 6-core system (so a total of 12 cores).

I have heard that in the past, Cubase had trouble with dual cpu systems. How does it work these days? I would be grateful for a statement from Steinberg and reports from Cubase users who have experiences with a transition to a dual cpu system and the performance boost one can expect.

The system runs on lowest buffer settings (32 samples) for live recordings with lots of plugins.

damn that will be one mother of a pc.

i got a new 6 core CPU and it works great with C5.5.3. but its not a Xeon and its not c6
