SLI/Crossfire scaling in ARR?

[Soukyuu]

CPU is a Phenom II X4 965@3.4GHz, utilization while running in a busy place (Ul'dah) is 50%/50%/50%/10%, running around in Thanalan has 50%/30%/30%/10%

It certainly is not bottlenecking me, else my fps wouldn't go from 30ish to constant 60 with Diablo 3 and 15ish to 40ish in unigine heaven bench.

it wont scale worth noticing since the game need more CPU then GPU but the game will run better then having 1 card.

...what? FFXIV is the biggest GPU monster out there due to it's shader-heavy engine, if FFXIV was CPU bound, then you wouldn't need a 670GTX to run it on max@60fps.
