Checked it last night, both the talent and the buff on the player state it's only for physical damage.

Armor cap is 49905.
Damage Reduction formula is %Reduction for 83 = (Armor / (Armor + 16635)) * 100
Chart assumes a 10k hit to make the math cleaner.
Armor doesn't scale linearly.

 
Armor	Dmg	DmgOld	DmgNew  Difference 
10000	6250	5710	5625    85 
24000	4100	3600	3690    -90 
40000	2940	2500	2646    -146 
42000	2840	2500	2556    -56

The first column is the targets armor.
The second being damage taken assuming no Inspiration or other DR buffs.
The third is damage taken under the +25% armor version of Inspiration.
The fourth is damage taken with new Inspiration.
The last column is the difference is damage taken, with positive numbers indicating new Inspiration does more damage reduction.

Old Inspiration stopped having an increase affect at around 40k armor due to the buff raising the target above the armor cap. Thus causing some of the buff to be wasted.

New Inspiration continues to work even at the armor cap. It scales better. That is why new Inspiration is better. As old Inspiration would have been next to useless by Icecrown. If not useless than at least not a good place to put 3 talent points since a good chunk of it would have been wasted.
