As far as I recall, it should be automatic for fullscreen apps in D3D9. SLI introduces some issues with synchronizing contents across the boards which can be tracked using appropriate profilers.
I'm still not quite sure SLI makes any sense for gaming but I'm fairly sure it makes no sense at all for learning. Even a low-end card will provide more than enough perf for you for the next years.
