There are some benchmarks on various tech sites on the 9800 GX2. It looks a bit crap if I'm honest. I mean in comparison. For example, two 8800GT's in SLI could probably outperform it and would cost around the same price. SO I'd like to know, what the heck has nVIdia done thats a real improvement over the past series?

I await the 9800GT and GTX benchmarks though. They are supposed to be released at the end of this month. The 3870 X2 is looking attractive to me right now and I usually prefer nVidia.
