Okay, so I've been researching this motherboard (clicky clicky!) for a while now and it's been coming along great until i found out that it had an onboard GPU. I wanted to put a different GPU but I don't know if that's possible. I know it has all this fancy 4k and all that jazz, but I have no need for it. My gpu is the Gigabyte GeForce GTX 770. please reply asap!
