Seeing some early bench results in the 3DMark threads, it does look like these cards will be the faster or possibly equal to Titans/780's however, on saying that, they do look like they need water to do that and a fair chunk of voltage but custom cards could be the telling point. I can see a binned chip on a Lightning under water beating out a Titan with little effort.
For the consumers, this is great news and AMD fans have a top top card at a fair price and the Nvidia fans have a top top card at a fair price, so win win for the consumer.
It's a piece of pee to get a reference 290X quicker than a Titan (on air obviously) on the reference cooler. If you're comparing apples to apples it's quicker more often than not! It's an awesome card
