I'm trying to decide if the 6970 or using two 6870's with crossfire would perform better. I was using this handy site to compare:

http://www.gpureview.com/show_cards.php?card1=638&card2=635#

I'm wondering, though, which of the statistics provided is more important?

x2 6870's: Better memory bandwidth, pixel/texture fill rate
or...
6970: Better GFLOPS and framebuffer

Which would perform better?

The 6870X2 would but the drivers aren't really "mature", so you may experience some problems or some game problems like low FPS.

Is it likely that the drivers would "mature" as you say? Or am I right to assume that AMD will focus on updating drivers for newer and upcoming products than spend time on that?

2X 6870s will be faster, but at this point it would be foolish to spend money on a 6XXX series card until the rest of the 7XXX line falls into place in February. You might get a quicker single card setup (better than the 2X6870) for the same, or less cash. Plus, you don't have to worry about crossfire profiles or microstutter.

I imagine that two 6870's may equal close to the same performance as a Radeon 7970 or 7950, but those are expensive. Increasing the card count will also result in greater power consumption and heat generation, you will be better served with a single high-end card.

as a long time user of crossfire, I love it, however If I were to choose, I would first off, wait until the complete line of 7xxx cards come out-and I would purchase the most powerful single card I can afford. The reason being is upgradeability. lets say you purchase two 6870s, well say a year from now their two slow your going to have to replace both of them (either with 2 more cards, or a single card) but if you get a single high end card, in a year from now if you need to upgrade and can't afford the latest and greatest, you can usually afford to get another matching card much cheaper used and double your performance. two 6970s will outperform two 6870s in a year. Thats just my two cents.
