Can anyone tell me how much time there usually is between the release of nVidia reference cards (or Founders Cards in this case) and the release of custom cards by other manufacturers like MSI, Gigabyte and Asus? I can't seem to find any information of the spread between releases both of the 700- and 900-series. I want to skip the Founders Card to go for a factory overclocked version with better overclocking capabilities. Thanks in advance for the answer(s)!
