Titan X vs 8GB, 16GB, 32GB, ++++?

[SiriusLeo86]

System Specs...
CPU: Intel i7 4790k
Motherboard: Gigabyte Z97X-UD5H-BK
Memory: 8GB Corsair XMP 1600 CL 8-8-8-24

I'm in the process of upgrading my memory to 16/32GB. I've read that the Titan X, "recommends" up to 48GB of memory to run, "properly". I've seen some reviews at 16GB/32GB that basically state there is no difference.

Here's my question... I've never seen a benchmark of a Titan X running with 8GB of system RAM... you think it'll be an issue till I upgrade to a larger quantity of system memory?

I'm not really planning on doing much overclocking on my CPU. So, what speed RAM should I get? I'm currently looking at, G.Skill 2400 16gb CL 10-12-12-31. Should I invest in more/faster RAM?

I guess the TL;DR of it is... what's the hubbub with the Titan X RAM requirements?

I dont think that GPU will require anything above than 32GB , 32GB is already a big overkill

As a follow up... Would you recommend these @ $119.99 - http://www.newegg.com/Product/Product.aspx?Item=N82E16820233778

Or these @ $139.99 - http://www.newegg.com/Product/Product.aspx?Item=N82E16820231589&cm_re=g.skill_16gb-_-20-231-589-_-Product

G.Skill has tighter timings at the same speed but it's been over 10 years since I've purchased anything from G.Skill.

I'm just getting 16GB for now and see how everything checks out once the GPU arrives.

Trident X are the best I've run with Haswell rigs and well worth it, also 16GB should be plenty

As you have money to burn you could get 32GB and then have a ram disk which would be amazballs.

Late to the party but I will leave this for future googlers. I accidentally bought two sticks of 4gb ram instead of two sticks of 8gb.

I have the evga sc Titan X and the machine works fine of 8gb. I did order 8 more gig but you can certainly get away with 8gb of ram.

I'm still getting 59fps on Witcher 3 in 1440 via DSR.
