Thanks both of you for the help, should I go with MSI gaming 3g or Saphire Vapor-x , or are the reference models ok? any opinions?
I've heard some issues with the fans on the MSI cards, and the Vapor-X have some heat issues (above normal core and VRM temps).
We have the Gigabyte WF3 280x, and they're amazing. Run nice and cool, undervolt like a champ (which then run even cooler!), and are whisper quiet. Very solid.
