Nice and good but it also has a disadvantage just to add some more vram onto a originally designed 2 gb card as already seen in the 3gb version of the 580. Furthermore there is still an over 5 year old small interface for this and the 4gb version also suffers from that.
Fact is that a 7970 ghz edition is currently in most cases as fast as a 680 and the review shows, that this overall is currently the fastest single card. Sure the pace is often only marginal, but we have several 680 users bite in their asses, that they bought it, because it is unfinished and expensive.
The 7970 users are quite happy now with the new drivers. 680 users not always. Just our impression of a small clan comunity with about 100 people. Some are benchmarkers as well and now tried out for months. It has a reason, why the review of the 7970 changed places in many cases in the race of the best single card.
I must say, that we are still waiting on a big kepler. If that hits markets somehow, ati will have quite a big problem. But for now the ati is more than just an alternative card for the 680. My opinion and the opinion of many.
