Hello! So recently Im building a cheap editing workstation off of old cheap hardware that I know will work (Please no judging) and recently I was rewatching a linustechtips moving vlog and videos in general as they help me learn more about pc components and how things work. In one of the videos it looked like his editor had a GTX Titan AND an nvidia being used in one system. I was really curious as to what uses there are in this and how does that work as well as uses for spare gpus or cheap gpus in general besides SLI. I'd really like to learn about this and curious if anyone could shed light on this.
