RAM bottleneck

Ram quantity and ram speed are different things. You need to look at your usage to decide how much is optimal. As for speed... how is the existing ram configured? Is it a single 8GB module, or two 4GB? Running two sticks in dual channel mode will double your memory bandwidth over a single stick. How much it matters again depends on what you do with it.

Yes I'd add another 8gb of ram, while most games still work fine on 8gb after you bump up the virtual memory/page file, I did have issues in some like Mirror's Edge Catalyst that would stutter like hell until crash and only got resolved with 16gb of ram, during gameplay I see total system ram usage around 10gb.

One thing I realized is that sometimes when you play a game that will use more ram but only has 8gb of ram in the system it will stay around 7 seeming like ram is not the issue but when you do add to 16gb total you'll see now 9~10gb usage without changing any thing else, so might seem more ram wasn't needed while it was.

please watch my test video and see the performance and tell me whats wrong in my case 
i7 4790k 4.6GHZ
GTX 1070 

8GB RAM

That is perhaps even better, since if you buy a the same kit again to make two sticks, you will be running them in duel channel which is faster. Mainstream CPUs perform faster with 2 sticks rathern than 1 or 4

so i i'll buy another 8GB same frequence.. do u think this wd help me in gaming ?

AC Origins is the ram for sure, CPU also gets hammered on this game so close all side and background applications when playing it, DDU in safe mode and reinstall the GPU drivers fresh new always good to do to ensure the GPU is working as optimal as it can.

all the application are closed here .. but the 100% cpu usage its beause the DRM of ubisoft .. she implemented another layer with Denuvo ..
