Has anyone tried those combinations? My current setup is P4 3.2GHz cpu 3MB memory and ASUS P4P800-E Deluxe and XP (32-bit, but do have access to 64-bit as well as Vista (technet dvd subscription)).

I get a lot of lagging due to lots of folders (working on setting subfolders) and end up doing firefly renders overnight. (i wouldn't think plain ol' pin-ups would tax my system.)
