Not faster due to the PCI-Express, but due to a default of 50MHz faster core speed and a 100MHz faster RAM speed. I think nVidia did this to counteract any performance hit's they may get due to their AGP to PCI-Express Bridge Chip. I have benchmarks here to, looking at this minute, and due to this slightly higher overclock, they are slightly faster, especially at a resolution of 1024x768 - about 20% increase in speed.
