Erm, in that "Very High" test, the X2 had the same minimum frames, and only four more than the 280. Now four frames is a lot for Crysis, when you're dipping into the low 20s, but if anyone knows anything about Crysis, it's that you can tweak it (using Vista, not the ghetto DX9 'hacks') and adjust it to get the same visuals, and in some cases better, with a lot of anomalies fixed, without having to run a FULL 'very high' system spec. Thus, when you're running solid 30+FPS and still retain Very High Shaders and Post Processing, the 'four' frames that make or break Crysis on stock settings, becomes a moot point. It's all down to minimum frames.
The X2 is supposed to be DOMINATING. Seriously, multi-gpu, with 2GIGS of DDR5...
There's only one game that even needs such power, and that would be Crysis, and it doesn't impress.
I'm still sticking by my initial prediction. That the X2 is a last ditch effort by ATi to take the fabled 'crown,' but is entirely impractical, and only serves to run their 4870 or maybe indirectly their 4850, sales into the ground.
For the amount of power required, heat output, driver dependability and etc. I hardly see why anyone except pure enthusiasts (a.k.a. synthetics) would bother.
If the GTX280 isn't fast 'enough' for someone, than the X2 won't be either, because their demands are simply too high.
My only appreciation for this X2 is that it MIGHT drive prices down on the GT200b, or in some form or another.
