Help comparing memory please

Getting a new build mainly for gaming, but also do Photoshop and some 3D work (3ds Max, Poser, etc.)
ASUS SABERTOOTH Z77
Intel Core i7-3770K Ivy Bridge 3.5GHz

Trying to decide between these 3, it's only about a $40 difference on newegg.

G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9D-16GXM Timing 9-9-9 Cas 9 <--- These are the blues, and I thought I read blues were the old models

G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL10D-16GBXL Timing 10-10-10-30 Cas 10 <--- Worse timing

G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBXL Timing 9-9-9-24 Cas 9 <---- Only 8 GB

I wish I could find a good 16gb (2 x 8 GB) with good timing, unless those blues are actually decent. Then again, I'm not sure if there are any drawbacks to going with 16GB that I'm not aware of. Thanks for any advice.
