Help deciding on DDR4 RAM for new rig

[harikirirocker]

Hi all,

So far, this is what will be in my rig:
ASUS RAMPAGE V EXTREME LGA 2011-v3 Intel X99 - mobo
Intel Core i7-5930K Haswell-E 6-Core 3.5GHz LGA 2011-v3 140W - CPU
EVGA 04G-2983-KR GeForce GTX 980 Superclocked 4GB 256-Bit GDDR5 ACX 2.0 PCI Express 3.0 - GPU

Now, as far as ram goes I'm debating between these two:
G.SKILL Ripjaws 4 series 16GB (4 x 4GB) 288-Pin DDR4 SDRAM DDR4 2666 (PC4-21300) Memory KitModel F4-2666C16Q-16GRB - Timing 16-16-16-36 - $229.99
VS
G.SKILL Ripjaws 4 series 16GB (4 x 4GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000) Desktop Memory Model F4-3000C15Q-16GRR - Timing 15-15-15-35 - $449.99

So, the price difference is huge. My question is do you think the timing, frequency, etc, is worth the huge price increase? I game fairly intensely on my PCs, but I'm not entirely sure what the practical difference on timing that close is (and frequency). I know a 2 hop down in timing is big, but is 1 that noticeable? Also, are there any models between the two that are better suited? Any input appreciated! Thanks!

dont think you would notice the difference getting the cheaper of those ddr4 kits

Go for the cheaper models, only a hardcore overclocker would notice the difference.

Yeah, you're probably right. With the rampage V I'm probably going to OC this to 2800 + anyway and be able to smoke anything for a while. Shouldn't be a bottleneck.
