I can't choose between these 2 motherboards, both of them is really good. Which of the Mobo is the best for gaming and video rendering? The Gigabyte Z77X-UD5H motherboard is expensive than the ROG board, but the ROG board has extra features.
If you need the extra features that the Asus board offers, go for that. Else go for whichever is cheaper. A motherboard does not make a computer better for gaming or video rendering. Other components determine the performance in that.
