8 GB RAM for gaming

[logicandreasoning]

When ever i game modern games like gears of war , far cry 4 , watch dogs 2 , resident evil 7 , gta 5 .. my ram usage doesn't cross 6 GB out of 8 .. on windows 8.1 .. but my pagefile usage crosses 10 GBs.. its the same on windows 10.
Is my RAM not enough for modern games ? The issue is something different ? My idle desktop RAM usage is 1.3-1.5 GB.
I've set manual page file in game drive only .. of 16 GBs..
Please guide if i need more RAM or the issue is settings related.

Specs:
I5 3470 @3.4 ghz.
8gb xms3 @1600mhz
Gforce 1060 gtx. 6 gb.

Your pagefile usage is telling you to ad more RAM.
