Don't get that cooler on the CPU. For a really good budget cooler I'd spend the money and get the Frio, its well worth it. Even the Cooler Master Hyper 212+ is a better cooler and can be found for under 25 dollars.
EDIT: Fixed, price is still the same as I accidently just added them twice.
I heard that the Twin Frozr III can also be unlocked to 6970.
I've also heard of the Twin Frozr III being unlockable. However, I think it's more hit or miss than with the Twin Frozr II. Either is a great choice, I have used a Twin Frozr II they run really cool and quiet.
