Unanswered question for Nvidia SLI

[Dahr]

I send the following question to Nvidia's Customer Care and never received an answer. I was hoping someone here might know.

I'm thinking about upgrading to a SLI capable motherboard and GPUs. My question is - I only play one video game (Dark Age of Camelot, Catacombs] and I play it in window-mode - is SLI supported in window-mode? Or will the game only run on one GPU with that configuration?

Thank you in advance.
