Wasn't thinking of crossfire with them, just a single card which would roughly = two 970's in a single card for about the same price. If there is a price drop coming I would sli 980's but I don't see that happening soon.
They 390x will have 7 gigs right? Any early indication on the price?

It's a dual GPU card, but the way it functions is no different from crossfire. It will be configured as crossfire in catalyst. The Hawaiis just didn't do as well in crossfire as Tahiti in terms of scaling, smoothness, and stability. And if you have a second monitor, you'll want to set those cards on fire (but that's a different story and irrelevant if you only have one monitor).
You probably knew this already, but if that "8GB" 295x2 really only has 8GB worth of chips on the entire card, then it doesn't really have 8GB of vram either. It still works like crossfire and 4GB will mirror the other 4GB.
The 390X will have 4GBs as well, but it's stacked HBM (high bandwidth memory). It will be limited to 4GB (as in, no AIBs making 8GB versions) until Hynix can produce higher density chips (right now the HBM cubes are limited to 1GB each and the 390x's memory bus would only be to handle 4 cubes total).
