eh whatever, the X1400 and X1300 are not nearly as good as a X1600 or near to an X700.
X1300 is about 1400 3dMarks05
X1400 is a overclocked X1300 getting about 2000 3DMarks... which is similiar to the X700.
As for the Go Series... just wait and watch till they release what they got... we are all curious...
But from what I've read STICK with ATI, because their GPU is VISTA compatable basicaly X300 and beyond will run Vista, plus ATI is offering alot of technology rite now...
As for Nvidia im not sure, but people say that they will start to offer similiar things just when vista is released...
Personaly im an Nvidia fan, but heck who cares who you like more... which ever offers better technology im game!

Thanks,
