f i buy any type of DDR3 1333 itll work?
In theory yes, the motherboard on the other hand may have other ideas. All motherboard manufacturers (or at least they should) have a QVL (Qualified Vendor List) of ram that they have tested, and is a good place to start with seeing what has been tested to work with the motherboard and go from there. The list isn't the be all and end all though as there is just too many different makes and models of ram, that and I don't think many if any of them update it after the motherboard is released.
In your case seeing as the G-Skill you have now works OK then the new stuff should too, but no guarantees.
