I'm wondering which 6970 GPU I should go with?
HIS?  MSI?  Sapphire?  Gigabyte?
I'm going to buy 2 of them, which card will overclock the best/produce more bitcoins?

I might get 2 of these.

I noticed someone mentioned bitcoin mining in one of the reviews, heh.

It doesn't really matter what brand...just find the cheapest one with a good warranty and you're all set.
Just make sure you keep the temps down. As to overclocking, your mileage may vary as even 2 6970's from the same manufacturer may have variances in its overclocking capability. Long story short, just pick your favorite brand and experiment with the clocks as only you will be able to determine how far you want to push the cards.

If you can find one, get a XFX 6970.

Doesn't differ from any other stock model, but they have double lifetime warranty, which means even if you sell it later, the 2nd hand buyer can register it & get life warranty on it.

You naturally also get lifetime warranty instead of 2 years, 5 years etc.
Improves the resale value by quite a bit.

Or if you're willing to overclock significantly, get a 6990 at almost the same price as two 6970's.
It contains two full 1536sp cores of the 6970's downclocked, but you can get both cores to 400mhash/s or better with OC'ing.

I have ASUS 6970. It runs by default @890Mhz (~70C) and delivers 380Mhash.
