I can already confirm very good scalability (with our workload) on
postgresql on that machine. We've been testing a 32thread/16G-version
and it shows near-linear scaling when enabling 1, 2, 4, 6 and 8 cores
(with all four threads enabled).

The threads are a bit less scalable, but still pretty good. Enabling 1,
2 or 4 threads for each core yields resp 60 and 130% extra performance.
