This is... Interesting. The benchmark results, I suppose, would reflect what the reference system used for its chipset; the nVidia ones would overclock the 9600GT automatically, while the Intel or AMD chipsets used for benchmarking would not.
Still, while it's a novel idea, I'm not yet entirely certain that it would be fully a good idea; this leaves a potential place for errors to arise, and as the article noted, could result, in some cases, of the system not POSTing. And if a piece of hardware, when not defective, won't POST successfully in your machine, it sucks no matter what the benchmarks say.
So here I'm waiting to see if there are any reports of problems with the 9600GT, before I make up my mind on it.
