Windows 7: Win7 64 Firewire PCIe Card That WORKS. - Anyone?

Need to hear from those of you who have a working PCIe firewire card in your Windows 7 64 desktop. I'll copy you! Firewire/Windows 7 is a widely known problem and the Most common fix cited is to use the legacy drivers. That does NOT work for most people nor for me. Anyone out there with card specifics? Some cards may work where others do not. My computer only has PCIe slots so I'm restricted to that particular type, no PCI.
Not looking for questions, such as... Have you updated your drivers? Do you have the latest windows updates? Please, no questions like that. Not a newbie. Assume I've done it all.
