There are no GT300 cards. On the desktop, nVidia's next graphics cards will be the GTX480 and GTX470. The benchmarks so far have those pegged from 10-15% faster than the ATi offerings (HD5850 and HD5870), which has just been rendered even more marginal with the latest ATi driver release and will continue to be rendered ever less important with each driver release. For a $100 premium, the nVidia isn't worth it. Any GT300s you will see on both desktop and laptop platforms are rehashes of old GT200 parts (desktop) or old G92 parts (laptop) to try and dupe you into spending a premium on technology two and three generations removed.

If you want a high-end card right now, go ATi. Better yet, wait for the GTX480 to release and then the ATi prices will lower to further strangle nVidia, which again means buy ATi.
