Before I ask my questions here are my 2 builds

First build (primary):
Case: CM HAF 932
Cpu: X4 750K
Gpu: Gigabyte R9 270x 2gb
Ram: 16GB Corsair Vengeance
MOBO: MSI FM2-A75 MA-E35
HDD: 1TB WD Black
SDD: 250 GB Samsung 840 Evo
PSU: Corsair CX750M

Second build:
Case: Rosewill Ranger- M
Cpu: I7 2600k
GPU: Asus GTX 660
Ram: 8GB Crucial Ballistix
MOBO: Intel DQ67OW
HDD: 160GB Seagate Barracuda (soon to be upgraded)
PSU: 500W Corsair CX500

On my first/primary build (AMD) I'm getting around 61 FPS on BF4 while on my secondary build (Intel/Nvidia) I'm getting around 71FPS, all on ultra.

Question 1: I know that the 270X is a better GPU then the 660 so is my X4 750K bottlenecking my 270X?
Question 2: If I swap my I7 2600K with the DQ67OW mobo from my second build into my first build what FPS gain should I see?
Question 3: If I swap my X4 750K with the FM2-A75MA-E35 mobo from my first build into my secondary build what FPS loss should I see?

Any help is appreciated. Thanks

I was going to try to swap them tomorrow but from pretty much every benchmark I've seen the 270X has performed better

+1 switch the gpu's around.

Play bf4 properly on the 2600k system.

I'll try switching the GPU's around tomorrow and keep you guys posted on what I get.
