Overclocking an i7-920 with 24GB RAM on an MSI Pro-E?

Update: Went with 6 x 4GB DDR3-1600 G.Skill Ripjaws. Easily overclocks to 4.0Ghz stable. Yay.


I need some more RAM. Rig is MSI Pro-E, Core i7-920, and Megahalem. I've got a single 4GB DDR3 1333 G.Skill right now:

Looking at either 6 of those, or 6 of the 4GB DDR3 1600 G.Skill:

Case is rackmount with 9 fans, so plenty of cooling, plus dual 120's on the Megahalem. Wondering if the 1600 is worth the extra cost for OC'ing, or if having 24GB is going to limit it too much and I should just save some cash and go with the 1333.
