As signature..
It is actually a Dell precision 7710
I originally bought to support some heavy duty database work (SQLServer, Oracle, Centura, PervasiveSQL). One of the Oracle DB was well over 500Gb with several hundred tables. The Xeon processor performed really well. At the time, 8Mb cache was quite a lot!
If I were to spec a new machine today, I'd probably look at one of the i7 based CPU but again look for a device with lots of cache memory.
