Question 2GB 1333 + 4GB 1600 vs. 4GB 1600

[Maclarin]

My computer is currently running a DDR3 2GB 1333 ram. I am planning to add/replace it with a DDR3 4GB 1600. Should I set it up with a total of 6GB but runs at 1333 or 4GB that runs at 1600? Also my computer is Acer Aspire M3970.

If 6GB does indeed run at 1333 and 4 GB runs at 1600....I'd go with the 6GB because I think the extra memory is more valuable than the 20% speed increase....although I'm sure there are situations where the 4 GB @ 1600 would be better.
