W7 here too.
Loving as well.
I had to use the legacy Firewire driver in order to get my RME FF800 to work... and that is on either the on board firewire and the TI card.
I am looking forward to upgrading the essential VST FX (schwa and Stillwell can ya hear me
) and trying that bit bridge thing... I'd love to see what a 64bit daw feels like with oodles of ramage.
greetings
