The term in the damage formula which modifies damage due to power (p) is:
(1+p/100,000)
The term in the damage formula which modifies damage due to percent damage boosting gear is
(1+d/100)
where d is the percent damage increase (e.g., for Heels of Fury, d = 3, for Shadowstalker +5 Ring, d = 2.5). Each piece of gear contributes its own multiplicative term of (1+d/100) and this value is not affected by power.
So if you have old pre-Mod 16 gear and you are thinking of switching it out for new Mod 16 gear with more power, then in order for the switch to be worth it, you would want the total power from the new gear but without the damage bonus, to yield more damage output than the old gear, with lower power but with the damage bonus.
Suppose p1 is the original power and p2 is the new power. Therefore, you would want:
(1+p2/100,000) > (1+p1/100,000)(1+d/100)
Doing a little bit of algebra, this condition is met when:
p2 > p1 + (100,000+p1)(d/100)
Example: if your original power is p1=120,000, and you are thinking of switching out your Heels of Fury (d=3) for some new gear, the new power would have to be at least:
p2 > 120,000 + (100,000+120,000)(3/100)
p2 > 126,600
in order for the tradeoff to be worthwhile.

I have not done extensive testing on this, but based on the tooltips (always a little dodgy), for the Primal Arms to be worthwhile, you want to determine if 1.05×p1 > p2, where p1 is the base power (without the proc) while wearing the Primal Arms, and p2 is the power while wearing the M16 gear.

What stacking rules are in effect now?
It used to be effects with the same name did not stack. But they did some changes to that because people complained about the Kino etc etc.
So what are stacking rules now?

Bonuses don't stack with 2 exceptions.
* Different ranks stack as with Shadowstalker +4/+5.
* Perk from Hags, Kiuno, Heels etc... stack with itself 2 times. So you can have Heels and Kiuno or replace either or both with the Melee Ebonized rings but you can't go 3x or 4x. Buff icon is present for this one.
