I was thinking of upgrading to a single 1080, wow dual 980's would be awesome! Right now I'm having my video card choke and go black if I move things around too much, so I know I'm going to have to do something soon. I have a GTX 750 Ti right now, and it is not cutting it. :( I am just getting back into rendering after a several year break, and it is amazing how obsolete my computer is now.
