Yes, indeed. That's why you should go for the very best card your budget can afford to go. Then, down the line, you can get a second one if, like someone said before, if the price and performance justifies it. Sometimes is just better to sell old card and get a new generation card.
I would not like to be in your shoes, honestly. On one side, you have very good, value-oriented AMD 7970 GHz edition cards and in the other side, you have very good, value-oriented GTX 770. Choosing between the two would be a nice headache to have, I suppose. The problem is that Crossfire really isn't the best option these days. I know for a fact because I just upgraded from a Crossfire setup the stutter and latency problems are noticeable. Only the GPU scaling - and the FPS -, is worthy. However, when you have lovely +60 FPS written in yellow on your screen, but the actual game feels like it's in the 20's, you know something is not right and your gaming experience gets hurt, a lot, trust me.
The thing is that AMD said is addressing this issue at this very moment. And a driver fix is schedule to this Summer. If this drivers happens, the HD7970 CF would become the best candidate to your purchase. Larger bandwidth and RAM will definitely help in the future.
But, as CF it is, the GTX 770 SLi is a better option, imo.
UNLESS, you can buy a GTX 780 right now! That would be the best of the best.
If your budget permits, just get one GTX 780 now and in a year or two, get a second one.
