Well other than the current hight price what makes GT2xx in your oppinions a worse product?

I mean the way I see it: it "seems" more power efficent and a better product package is built around that chip than a complete product package of 4870.
4850 is a killer product on the other hand, but 4870 feels like a bit of a hack job, but priced reasonably.
IMO only negative for GT2xx is the current price.
