I'm researching for my first time building a PC, which will be mainly for gaming, and I'm wondering which would be better for gaming? Or is it pretty much a wash?

1866 with a CAS of 9
or
1600 with a CAS of 7

Depends on your system there wont' be a big difference between them. Honestly the 1600 CL7 ram is better than the 1866 ram in this case. It could easily be oced to 1866 CL9, probably CL8 if you put enough time trying it. If they are the same price and you're not opposed to playing with setting get the 1600 not the 1866.

The 1600 CL7 sticks are better sticks to begin with even if he is OCing they would be better, just have to manually make them 1866 since the XMP profile will be for 1600.

Of the two, as Supahos said the 1600/7 would be the better of the two with a caveat - if it's a 1.5 volt (or lower set) - should run 1866/8 easily and prob 2133/10 - again. if it's 1.5 or lower - if it's rated 1.65 then don't even touch it, they are basically already at max normally

I'm looking at different types of g.skill memory which are at 1.5v, as for the rest of the build I'm thinking an i7 4770k with an asus sabertooth mobo, so I can't go beyond 1.55v as I think that is the limit for that hardware

That 1.55v limit means nothing, its just that as you see there is no need for 1600 MHz memory to go beyond 1.5v anything more means its worse memory that is being hidden by higher voltage. Those 1600 CL7 Gskill sticks will easily do 1866 @ CL8 (or they should) with 1.55v maybe even 1.5v.

-----------------------------------------

Those sticks would be good - the 1.5 thing is primarily aimed at the CPU at stock and DRAM being 1600 - I normally suggest 1.5 for 1866 and under sticks, 1.6-1.65 is perfectly fine for faster sticks (2133 and above) and keep in mind Haswell loves faster DRAM so with today's prices might even be looking to 1866/2133 or even higher.

Thank you for the article. Should I choose a different mobo other than the sabertooth? Asus says the sabertooth is meant to work with 1600 and 1866. I've been thinking Asus because they have a good reputation and an easy to use BIOS that is good for a first time builder and OCer.
