I'm trying to figure out what the differences are between the FusionHDTV5 Express and the FusionHDTV5-RT Gold Plus. Does one have a better tuner than the other?

Anybody know how the tuner in the FusionHDTV5 USB Gold is by comparison? Would it be practical to use with a Centrino notebook and a 120GB drive?

Thanks!

Aren't they the same, but one's PCI, and the other's PCI Express.
