Do you know if the computer was using all the processing power of the two cards, just not utilizing the VRAM, or if it was only using/recognizing the presence of one card? You said it was a quick test so I totally understand if you didn't pry that closely, but the way you said VRAM made me wonder....

Totally brainstorming here without having done much (any) research, but I would be really curious if a system could have two graphics cards, maybe even NOT SLI'd together, and software could split the 5 wow client (or Rift client) graphics load onto different cards much like ISBoxer does with picking which core to run the client threads on. As I understand ISBoxer, it's not locked strictly and exclusively to the chosen core alone, it's simply a priority system for distribution of the load across the CPU, but the idea is interesting to me. Of course, it would be even better if I could afford a system like that, but hey, it's fun to think about
