The only difference I can find between the two is that one model number contains BP and one model contains CG. What's the difference?

as usual newegg is a little bit wrong.

The chips that carry the "CG" code name in the SKU are E4 stepping, while the BP model is E3
As such the E3 stepping does not support SSE3, yet newegg shows teh BP as supporting SSE3 which i believe is wrong
