I recently ordered a Dell Precision 490 workstation with a single Xeon
5160 (Woodcrest) CPU instead of the Xeon 5080 (Dempsey) CPU. My reasons
was a cooler CPU (85W vs 130W Peak TDP) and a faster, more effective CPU
(4MB shared vs 2MB per core L2 Cache, 1333 MHz vs 1066 MHz FSB speed).
Dell's 490 price with Xeon 5160 was lower than for an equally configured
390 single socket workstation with the slower Core 2 Duo Extreme 2.93

The following benchmark by Phoronix with FC5 Linux proves that even the
2,66 GHz Xeon 5150 in general is faster than the 3,77 GHz Xeon 5080 with
exception for little lower RAMspeed

The new Mac Pro is also based on Xeon 51XX Woodcrest:
