[citation][nom]blazorthon[/nom]Excluding the apparent Enduro issue, Radeon 7970M>GTX 680M. The 680M is just a GTX 670 with the memory bandwidth cut almost in half (as well as a minor GPU clock frequency drop IIRC, but that's not as important in this case). Even the GTX 660 and 660 Ti have a substantial memory bandwidth advantage. The 680M has a greater memory bandwidth bottle-neck than Llano and is undoubtedly absolute crap in comparison to the 7970M and possibly even older cards too when AA is used. Hopefully, AMD will fix this issue soon, but honestly, I'm not getting my hopes up on that one. They are really taking their time with it and that's just abusing their customers.[/citation]
I've got 7970M in crossfire, and as far as my web-searching goes, they are neck-neck comparable with the SLI 680M. I wouldn't go as far as to say 7970M > 680M.
I'm told the 7970M overclocks beautifully too, but where I am now, with ambient temps of 35C, I don't care to try, but I wonder if you mean it is better in the overclocked state?
As for the driver issue, I installed Catalyst 12.9 beta 2 days ago, and so far it is running sweet. Only one crash so far, and I must say that *may* be due to the fact I'm trying to get my four SODIMMs to run 1866MHz @ CAS9, which thus far is not stable.
