After emailing Gigabyte support, they have told me that for the F2 bios, the DH folder version is for DVI/HDMI inputs and the DP folder version is for Display Port inputs. However, after trying the new Bios update, I have noticed my overclock not able to obtain greater than 2012Mhz, so I'd advised against updating if you have no problems with the card. The Bios update did not improve performance and is most likely not necessary at least from my experience. I have since restored my bios to the F1 version. Hope that helps.
