I recently bought a Dell D820 (2.33Ghz Core 2 duo, 2 GB ram, external 7200 hard drive) and would like to buy an Mbox so I can use PTLE live on gigs to play Ivory and other soft synths. I wont be doing much live recording, so the amount of ins and outs are not important.
My main concern is performance...particularly latency, while using large sampled pianos like Ivory.
My question is, would the Mbox 2 Pro Firewire give better performance (latency, pops clicks etc) than the Mbox 2 USB?
If not I wont spend the extra $$$'s on the firewire model..

(I'd be using a SIIG 1394 card bus if I went firewire)

Any input appreciated
