That mobo is kinda old don't you think? If you're currently using it, maybe all of your pc parts are outdated too, i'd recommend you to check them one by one to see if it's possible an upgrade.
About the mobo, I'd recommend you to change it if you want to use w10 properly ( Asus has a good variety of w10 mobos ). For GPU, the GTX 970 always suffice, you could try it.
