RAM for Asus P7P55D-E Pro

[Macksujin]

Hey all,

I'm looking for a few pointers regarding upgrading the RAM in my P7P55D-E Pro.

Current setup:
Asus P7P55D-E Pro with an i5 750
ATI Radeon HD 5770
4GB (2 x 2GB) PC10666 DDR3 1333mHz Dual Channel - G.skill NQ series.

I want to upgrade to 8GB in a 2 x 4GB arrangement and move up to 1600mHz.
I've been looking at;
Sniper: F3-12800CL9D-8GBSR
Ripjaws: F3-12800CL9D-8GBRL

Am I on the right track? any other suggestions? and whats the difference between the two I've suggested? they appear around the same price.
Any help is much appreciated
Cheers

Either of those should work fine, believe they use slightly different ICs and the programming is a bit different
