Which company makes the ati 7970

If you are looking for stock (reference design, no overclock or change in cooler) ones, I think you should go with sapphire. It's usually the one that is most reliable and the price weren't too high (they are priced good). Another alternative is XFX, it's usually as reliable as sapphire and it has double lifetime warranty, but the problem is that it's usually more expensive. But if you are getting the ones that has aftermarket cooler, you can get XFX Double D BE or Direct CU II, you can also wait for Twin Frozer III or IceQ. I personally would wait, The Twin Frozer III is usually best but very expensive and IceQ is more quiet and more price-to-performance. You decide overall.
