I agree with most of what Kit said except the following:

The maximum memory I can access with a Mac Pro 8 GB, OS 10.5 (Leopard)
is 1625 MB (set mem 1625m) which actually allocates 1711 according to
Stata.

We have just purchased one for our department (4-core) and I have consulted with one of our research centers who are considering getting one (8-core) for their high-end needs. The default MacPro config is 8-core. The 8-core Stata/MP is pricey, but the 4-core version of Stata/MP is more affordable.
Earlier this year we made the same choices that Kit suggests for our
group. And we have been very happy with the results. Although I am a
very strong Stata fan, I must say that I unhappy at the pricing for MP
Stata, and hope that Stata may rethink multi-core pricing some day. In
the mean, as Kit has done, I use 4-core Stata on my 8-core machine.
