I'm going to go pickup the new computer today. It has two 120gb HDs.

What would the best setup be?

HD1: Windows XP, Gentoo Linux, Main Backup Partition
HD2: XP Backup Partition, Gentoo Backup Partition, Windows Virtual Memory file Partition, Linux Virtual Memory file Partition, Secondary Backup Partition

There's speed improvement if I allocate the space for the virtual memory on the HD that doesn't have the OS's, right?
