ALso upgrading my system for better performance here, moving to at least 1GB of DDR400 dual channel memory (with a P4 3.0ghz CPU) the Mobo had 800Mhz FSB & SATA RAid onboard). I'm setting up a RAID 0 array (2 x 160GB 7200 drives). would I see a performance hit if everything is on the RAID drives (XP Pro, P^ & Swap, all on seperate partitions), or should I still use a 2nd SATA drive for just XP & a backup partition & put everything Poser related & swap file on the RAID for best speed?
