Yes the 580 is the fastest, unless you consider the gtx590 which is a
dual GPU card, but at a bit lower speed than the 580.  I think you said
earlier that there wasn't much gained having more than two GPUs though,
so a pair of the 580s would be the fastest.

Of course a pair of 580s would use about 180W more than your pair of
460s as far as I can tell.
