Possibly a dumb question... (5850 versions?)

Hi all. So, I'm basically debating getting a 2nd 5850 for crossfire. I was browsing current prices and selection at some local retailers. Specifically looking at Sapphire cards since that's what I already have.
Anyway, it appears that they are using a new heat sink. I'm wondering if anyone has a little more knowledge into it. They labelled the exact card I bought as the Game Edition. I also saw that a local retailer has a version that comes with CoD: MW2, but it's using the different heat sink design. So is it just an updated heat sink? I kind of want them to be identical - you know, mild OCD type thing - but I guess if the only difference is the cooling capacity then it's not a big deal. I think I can still get my version, although the Dirt 2 copy will go to waste (or a friend). Mainly I just want to be able to OC the new one without an restrictions - I've heard some cards need to be BIOS flashed to OC. Curently my 5850 is at 985/1200 max OC with a little more voltage (1.237V) and temps are fine, burn tests max out at 78C. If they're the exact same card tho... I guess the better cooler can be the top slot since it has less room to breath.

Solution
Hmm, actually a very important question. The new version does not have a black PCB, that means it has a Sapphire custom one. That means it could have the non-software-adjustable VREGs. Browse around for things like Sapphire OCing or even Newegg reviews to see if it still can have the voltage adjusted.
