Gigabyte GA-MA78GM-S2HP is absolutely fine.
Make sure you get the same model number. Like if you get GA-MA78GM-S2H instaed of GA-MA78GM-S2HP, Onboard DTS will be missing, which I think is not a big issue if there is a good price drop. All this onboard DTS and Dolby digital are just software features in these Motherboards..
And if you can get MA-78GPM-DS2H for around 5K, go for it as it has 128mb DDR3 sideport memory and all solid capacitor design.
