I just bought a computer (w/Windows 7) for recording purposes and now need to buy a PCI firewire card to connect my Saffire Pro 40 to it. What card(s) do you recommend I should buy? I know it has to have a Texas Instruments chipset but other than that? Are all the cards with that chipset compatible with Windows 7? I have read a lot of discussions about people having troubles with Windows 7 and PCI firewire cards so just wanted to ask what card people here are using with W7. Thanks
