Penryns 1333mHz Bus limits overclocking?

Wondering what peoples thoughts are on Penryns running 333FSB as standard. This means that comparing to a Conroe (266mHZ) clocked at the same speed, they have lower mulitpliers. Unless your running an Extreme model with unlocked mulitplier, isn't that going to limit your overclock? So the cheapest quad Penryn the Q9300 runs at 2.5Ghz stock with a 7.5 multi and the Q6660 runs at 2.4Ghz but with a 9 multi. So if you have a WCing and a suitable MB, A 400FSB will get the Q6660 to 3.6GHz, but the Q9300 will need all of 480FSb on the MB to get to the same clock. Sure its going to run cooler, but I guess not many people will have MB and ram capable of running a 480FSB stabley long term. If your on air cooling then the Penryns may be a better bet, but if your have WC I wonder if the higher multi Conroes would OC higher?

So its looks like those Penryns are for cool running rather than Max overclock.

I dunno, that screenshot from weescott although not necessarily stable is a 1.1ghz OC... not to be sniffed at.

True, but the Q9550 is going to be a £300 and up chip when released. Plenty of cheap Q6600's are doing that clock. The Penryns with high multi have shown to get well over 4Ghz on air, but its the cheaper low multi quads I'd be interested in. If it looks like the cheaper Penryns wont clock especially well, I might just plump for a Q6600.
