I could try to talk about the 780G chipset, but why do that when there's an excellent review
on that exact motherboard here at TR. Look on page 8 to see exactly how [un]suitable the chipset is for gaming. If you want to play games, you'll want a discrete video card. How much to spend and which one to get depends on how much you play games and what you expect out of them.
