the purpose of the thermal compound is to make the heatsink and the cpu's heatspreader 1 contiguous unit. allowing as much heat to leave the cpu into the heatsink is always the main goal regardless of how much or little heat is created.
that being said, use the best compound ya got for both, and you'll be ok. some of the medium range priced arctic silver is pretty nice.
EDIT--- BAAHHH... i see what you mean. if your cheap ass CPU comes with cheap ass thermal compound, DON'T use said same cheap ass compound for a pricey GPU.
