I have here a gtx 770 and three monitors. I want to reserve as much resources for my 770 for games as possible, but I like to watch twitch and youtube on the side while I play demanding games. I threw in an old gt 8500 I had laying around hoping that it would render youtube and twitch and save my main gpu from the extra work. But according to EVGA precision, I'm getting 50% load on the 770 at a 135 mhz clock and 30% load on the 8500 with a twitch stream running full screen on the side. So they're both working to render the same thing? Is there anyway to control this?
