My 11 yr old son has an Ibuypower desktop with a NVIDIA GeForce GT 710 graphics card. He's got 8G RAM, 3.5 Processor (FX-6300), 1TB hard drive. He wants to upgrade the graphics card but I'm not sure how much he can with the other computer specs. He plays action/sports games and streams a lot. Would a 1070 or 1080 8GB card be too much without any other upgrades? Any help would be appreciated. Thanks!
