Need some pro gamer/builder advice

[talelorm]

i want to buy these

GIGABYTE AORUS GA-Z270X-Gaming 7 $239.99
i7-7700K
Corsair DOMINATOR Platinum Series 32GB (4 x 8GB) DDR4 DRAM 2133MHz C10 Memory Kit
CMD32GX4M4B2133C10
Timings: 10-12-12-31 1.35v
price:$328.99
my question is: is the c10 kit worth it? should i save some money and get the 16gb kit for 200?
im going to be 4k gaming with a 1080Ti asus rog edition
my powersupply is a seasonic platinum 1000w
i really cant decide or find any information about these particular sticks that show them worth buying . Just that they have really good timings, nor information on how much ram 4k gaming on high end games like battlefield 1 consume.
thank you for your time

16GB is plenty for gaming. Most games don't even reach 12GB of ram usage.

hmm, even with a 7700k overclock and 2x 180 tdp gpu, u would only need a good quality 850w psu. so for a 1080ti 650w is enough.
and as for having a z270 mobo, y restrict to 2133mhz? go all the way to a 3000mhz
and yes 16 gigs is enough. 2x8gb

There are so many variations of it on their page, it would take all day to look at them all... but here is a 4x4gb set at 2400mhz (native kaby lake speed) with the same CAS

I can't see spending that much money on the 32gb version considering 16gb is seen as high end on a gaming focused setup. not to mention the CAS, which is better than what 99% of people have also. seems like overkill when considering any more than 16gb
