Well, gaming on Vista isn't great right now, so drivers do need some "major" work.
I am not going to disagree per se, but my HP laptop does a fair job at gaming. Now given that it is new and I don't have a real "base line" to compare against its potential, you could easily be right. The GF 7600 does pretty well for being a midrange card in Lineage II and such.
I really only see an upside to nVidia performance in the future. nVidia's drivers do always need work... damn higher overhead. :?
