I honestly cannot remember exactly what it would hit but based of the last time which was the other day when messing around, I hit this on 3DMark Firestrike Extreme.

I was thinking of watercooling this card a while ago, but since there is a possibility of me getting a new job soon with a major salary increase (45%) I will be able to basically build a whole new machine, and that will be in a desk not a normal case.
As I say at least it seems Asus is actually showing what it will boost to, instead of a number around the "FE Cards" boost clock which again the FE's boost higher than the advertised boost clock.
