I'm in the process of setting up a live performance VST rig and trying to figure out which audio interface to buy.

i'm running a toshiba satellite a505d, amd dual core 2.5Ghz, 4GB ram, Win7, 4 USB 2.0, 1 ExpressCard slot (NO Firewire)

i'm using brainspawn forte as my vst host, running all kinds of VSTs

is the Multiface II / HDSPe ExpressCard combo a viable option for me? if so, what are the main considerations if deciding between that and the fireface UC?
