If you're concerned with performance, you should definitely get the K-series
server. The 64-bit chip will be available in a few months and it doubles the
performance of current systems. Benchmark numbers released:

                     HP       IBM         SUN          DEC       MIPS
                  PA-8000  PowerPC620  UltraSparc  Alpha 21164  R10000 
                  (180MHz)  (133MHz)    (167MHz)     (400MHz)  (200MHz)
SPECint95           11.8    5.6*/**       5.6        11.0 **     8.9 
SPECfp95            20.2    5.6* /**      9.1        14.0 **    12.5

HP also supports PVM on the K-series and Fiber-channel clusters.
