Hi all,

Just to be clear....

My old VT3 system uses the P4DCe+ supermicro mobo. It has two 64bit/66mhz PCI-X slots and foour 32bit/33mhz PCI slots.

The manual suggests that you put the SCSI controller on one 64bit slot and the VT3 card on a 32bit slot. The SCSI controller is a 64bit/133mhz.

1. Would there be any noticable VT3 performance benefit to upgrading my mobo to one that has at least 133mhz 64bit PCI-X slots for use with the 133mhz SCSI controller?

2. Would there be any noticable VT3 performance benefit to upgrading my mobo to one that has at least a 800 or higher system bus speed.

If I upgrade to the VT5, the specs indicate that scsi is no longer required since it only refers to software-striped SATA drives for video storage and playback. Also the VT5 card, while still 32bit its now 66mhz, can go into a PCI-X 64bit/66mhz slot for better performance.

2. The only reason to upgrade my mobo for the VT5 would be to take advantage of higher system bus speeds of 800 or higher that the VT5 requires?
