Feel free to correct me if I'm wrong here, guys, I've yet to test this myself.
That's actually wrong. My Core i7-860/GTX460 setup has a pair of GTX460s. There is a SLI bridge on the cards (I enable SLI when I game on it), but SLI is disabled, and only the first card has a monitor hooked up to it. Both crunch at the same speed
