That chart says you can, although I'm not sure it would be any better than doing so with another 5870, which would be much cheaper.

Technically, it would be a trifire setup as the 5970 has two 5870 cores (but has lower clock speeds). While crossfire scales pretty well, trifire doesn't scale all that well. What resolution do you play at? It most likely isn't worth going beyond a 2nd 5870 for most setups.
