I know the MSI are voltage unlocked. So overclocking is simple with msi afterburner.

I have 1 x MSI Twin Frozr, 2 x Power Color and a 1 x Vision Tek.  The MSI is a much better card than the other two.  The default clock is much higher than the others (960 vs 925 and 800), and I was able to overclock to MSI to the point of getting over 600 MHash/sec, which is in the 7970 range for $100 less.  I have only had it for a couple weeks, but pretty happy so far...

I love the sapphires - esp for in case designs. Great fans, voltage unlocked, great to OC. Running 3 right now @1700 mh/s total just under 650W for the cards. Temps in closed case ~70C.

So what? If they're cool, quiet, and pull good numbers, why do you want it unlocked?

Tips? 1crazy8pMqgwJ7tX7ZPZmyPwFbc6xZKM9

yup they are, but still are able to get ~600-603 mh/s, stable 65C ~70% fan, milk crate rig so there is plenty of air to flow.

I just built a rig with 3x XFX 7950's and I concur with hem sucking... i have to push them pretty far on the OC to get ~520 ea and they run hot with the alum surrounding the heatsync.  My MSI 7870's hit 475 w/ barely overclocking and eve an HIS 7950 gets 550.

So from what i've read MSI hit 600+ easely...I thought about sapphires but MSI (also heard that HIS can hit 630KH) seams the way to go.

out of that list sapp and MSI TF are the best. for OC it's same as lottery. Your chip may not oc or do very well.
I have a MSI card running that can do over 1200 on core stable with small v bump mining btc and ltc. getting 640 kh on ltc atm.
air cooled, and doesn't go over 80C
