You can't. The NV43 core only has 8 pixel pipelines and 4 vertex shaders maximum. Only the NV43-V (also known as the 6600 LE) has 4 pixel pipelines and 4 vertex shaders. I'm not sure if you can unlock them though...
If you're gonna get a 6800 NU, get the 6800 GS instead. The PCI-E is the NV42 core manufactured with the 110nm process instead of the NV40 and NV43's 130nm process. 12 pixel pipelines and 5 vertex shaders, although this is exact to the 6800 NU's specifications, the 6800 GS has 256mb GDDR3 on a 256-bit interface instead of the 6800 NU's 128mb DDR on a 128-bit interface. Also, the 6800 GS has a faster clock, allowing it to be cheaper and faster then the 6800 GT.
