Does Windows 7 support the "Matrox Millennium G550 PCIe 1X Graphics Card"?__
I checked with their Tech Support and received the answer that they "might" have Win7 drivers sometime in mid-2010! Which is kind of a long ways out ...
According to the
Compatibility Center the Maxtrox Millennium G450 is compatible. Since that is a older version i would think that the G550 would be supported as well. According to the site no action was required either. So you might have hope till they decide to get
proper drivers out.
