G.Skill Ripjaws 4 model difference

[json101]

I am looking to build my first "entry-level enthusiast pc" (in my words). I have been looking at memory for a while, and I have decided I will probably get the G.Skill Ripjaws 4 16GB kit, however I can't figure out why there is a $50 difference between these two kits: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231822&cm_re=F4-3000C15Q-16GRBB-_-20-231-822-_-Product
and

I can see that there is a slight timing difference (15-15-15-35 as compared to 15-16-16-35), but are those two -1 tighter timings really worth the price difference? I can't figure out why these two models of memory are so different in price. Can someone help me understand? And is the extra $50 worth it?

Thanks in advance!

Sort of wondering if it may be they got a good deal on the sticks or simply a sales promotion, they show the regular price as $179.99 and marked down to $149.99 - great price!

Thanks for the quick reply. That's kind of what I was thinking. But just out of curiosity, (since I'm fairly new to this "enthusiast" stuff) how much performance increase do those timings really give? I mean, would a 15-15-15-35 still be worth $20 more than a 15-16-16-35?

Basically none, the primary timing is the CL (or first of the timings) as far as affecting performance, lower is better, the others are more to keep things stable at the given CL
