Get the ASrock Z75 Pro3. It has all the features of the gigabyte one you mentioned, and it has a better chipset which supports overclocking. H77 doesn't. Plus, the Pro3 is cheaper.
Use the saved $ to get a better CPU or video card if your friend hasn't bought it already. Spending $130 on a motherboard is way too much if you're using a radeon HD 7770.
