Paolo, I'm considering a reformat soon and I'm very tempted to go for this once I get the new installation up and running.
What you said about it auto-configuring sounds great, but can you advise on whether or not I'd be better off leaving the SLI connector in place?

My system has two old GTX460 cards, and there's a little bridge connection (a physical one) that can be used or not.  How would Reality prefer the system do you think, with or without the SLI connector in place?  I should point out that I don't use the system for games, so that's not important, but if it makes a difference to Reality and rendering performance, I'm quite happy to leave it off because I read somewhere that having it on can actually impair performance with some things.

If you know which way Reality would prefer it, to get better performance, I could set it up as such before I started a new installation.
