Possible uses for second core

Could a second cpu core be used as a physics processor? If so would it be worthwhile to use it as such. I am also curious about software rendering with a second core. If the entire second core was used for software rendering what speed would it eqaute to of a dedicated gpu. For example my system has a 6150le for video would using the second core to render graphics be faster, slower, or equal to the 6150 in terms of speed.
 
here,

Q: Can't you just use a dual-core CPU to do physics?
A: Not according to Ageia or Havok. They report that a dual-core CPU can handle about 1,000 objects. CPUs are designed with “general purpose” computing in mind. This is a good thing, because CPUs are very versatile. However, like a GPU, a PPU is designed specifically to process physics calculations, and this specific engineering allows a PPU to handle up to 20,000 objects, according to Ageia. A GPU, by nature, is more prepared to handle physics calculations than a CPU, and therefore can handle “thousands” of objects, according to Havok.
 
Here's another article link that you may find of particular note.

While it's true that a dedicated PPU (Aegia) would be premier for physics, a dual-core processor is still going to provide a jump over a single core setup. Unlike a PPU, which may or may not catch on, developers for good solid multi-threaded games will be able to also handle Quad-core and more. In time you may see this scale considerably, especially if AMD+ATI end up with the GPU/CPU. It's for so much more than integrated graphics, you'd have a large number of parallel processing streaming processors for that physics calcualation (esentially the GPGPU that ATI and nVIDIA are looking at externally brought into the CPU).

PPU's currently are not matched for performance, but the scalling we should see in CPU cores will eventually push them out in my opinion.
 
I guess I was thinking something along the lines of a modified processor driver that can be switched from dual core mode to one core and one physics mode. For games that do not support multithreading the second core would work in conjunction with the video card for a performace boost. Somewhat like SLI but with one core and the video card instead of 2 video cards.
