Steve, here is how it works. Both cards have the EXACT same memory states when SLI is working. This means either you'll have 320 megabytes of video memory available, from the point of view of directX, or it won't work at all.

Anyhow, both cards have the same data in memory, and each card is instructed to spend it's time drawing some of the frames. Therefore, while SLI can be much faster, you'll never have more available video memory for games than the memory of one card. It IS using the ram on both cards, but games can effectively access only one.
