Both - running an Athlon64, 32bit PCI slot, 2 mirrored drives and a quad 
opteron, pci-x, 4 raid 0 drives.

The driver in the FC4 kernel is 2.26.02.002 (grep -i 
version /lib/modules/2.6.11-1.1369_FC4/kernel/drivers/scsi/3w-9xxx.ko) 
while the driver that amcc has is 2.26.03.015fw (grep TW_DRIVER_VERSION 
3w-9xxx.c) Its not that great a difference but it might be worth it for you. 
Don't forget to check the firmware upgrades as well.

High is relative... Sometimes a simple script can create a ton of IO for just 
a few seconds and that can be enough. :-)
