ok so i have a radeon 7870 laying around unused and i was woundering if i could youse it to display the monitor and use my gtx 680 to do all the hard work like rendering, gaming and all the rest. or i use the 680 for gaming and the 7870 for display and video rendering so i can play a game without lag whilst its rendering. or does it not work at all the way im thinking. i know a nvidia can be used for phisx with a ati card being the main card but can it go the other way around sort of?
