Adding more RAM at different speeds? Will it impact performance as much as to make it worse than without adding it?

upgrade

I got a new laptop with 4GBs of ram, expandable to 8GBs. It has 1 4GB stick DDR3 PC3-12800 at 1600Mhz. I can't seem to find another one exactly the same locally, the closest I've found is 1 4GB stick DDR3 PC3-10600 at 1333Mhz. So my question is, I know they will both run at the slowest speed, so even if I have more available RAM it will become slower. Is the performance loss big enough to make the upgrade not worth the hassle?
