I let my computer(s) search for E.T. in their free time-
And I just finished building my new P4 Prescott and noticed a difference in performance from my 1.7 Willamette
Old Computer
P4 Willamette 1.7gHz
1.5GB PC800 RAMBUS
New Computer
P4 Prescott - 3.2gHz, 1MB L3
1GB PC3500 2-2-2
SCSI and SATA RAID; U320
I've also run some benchmarks; generally they all tell me I've made a >4x improvement in performance across the board.
