Currently, the 7950GTX is the top dog but the 7900GTX isn't far behind for less money. I was recently in the market for a gaming laptop and was going to go for one with the 7900GS due to the price/performance factor, but since I don't really need the portability that a laptop offers I decided I might as well wait until the mobile 8800 GPUs start appearing. If the performance leap from the 7900 --> 8800 series for desktops was any indication, laptop gamers will be in for a real treat with the Go8800!
