For those of you looking for a broader review. www.Anandtech.com has both dual GT680s and dual 4870 X2s. While I dont usually like their style of review. It does complete the picture of how truly awesome the 4870 X2 is. In reality AMD never claimed that the 4870 was ever supposed to be a top contender. Which is why the price point was so much lower. It was really just a disappointing release from nVidia that caused it to compete so well. That's not to say the GTX 280 doesnt perform well. But it does leave much to be desired for the price point. Considering that AMD was looking to compete with nVidias mid range and ended up taking on their top end. The 4870 X2 was the card that was intended to compete with the GTX 280. I don't think AMD expected to dominate the way it did, in both price and performance.
