That would suggest you have a bottleneck with the CPU. I suggest trying to overclock that CPU to 3.6GHz.

What resolution are you running? What game are you playing?

Are you getting the same performance as before? Do you have vertical sync enabled in the NVCP or frame rate target enabled in precision? If so disable them.

Where it lists...
Performance Log
Frame Rate Target
Profiles
 
All you have to do is click Frame Rate Target and see if it's enabled or disabled.
 

Any new BF3 patches lately? Maybe a new patch put a cap on the fps, which would lower the usage because of the cap. Do you have vertical sync disabled in BF3 also? Are you running BF3 with max settings? Maybe the older version of precision doesn't read the usage correctly when using your new monitor, so you need to update to the latest version. (I doubt this is the issue but try it anyways) What happens when you run unigine heaven 3.0 at max settings does it show %99 usage on the osd? If it does then it's probably something to do with BF3.
 
You could also try reinstalling the latest video drivers following this guide to see if it corrects the issue...

#1 Download & Install Driver Sweeper & CCleaner.

#2 Uninstall NVIDIA Graphics Driver, NVIDIA 3D Vision Controller Driver, NVIDIA 3D Vision Driver, NVIDIA HD Audio Driver, NVIDIA Update,  NVIDIA PhysX Driver from Add/Remove Programs.
#3 Run Driver Sweeper and Select NVIDIA - Display & NVIDIA - PhysX and click clean. Click No for Reboot.
#4 Run CCleaner and use the Registry Cleaner and Scan for Issues and then click Fix Selected Issues. (Backup the registry just in case something happens)
#5 Reboot your system
#6 Repeat Steps #3 & #4
#7 Download the lastest driver from http://www.nvidia.com/Dow.oad/Find.aspx?lang=en-us
#8 Run the downloaded driver and select Custom (Advanced) Install.
#9 Deselect the following if you are not using them... 3D Vision Controller Driver, 3D Vision Driver, HD Audio Driver, NVIDIA Update. (Only things you should have selected are the Graphics Driver & PhysX System Software)
#10 Select Perform a clean installation then click next to install the driver.
 

So is there a voltage tuner that comes along with the 3.0.3 version?

So you had version 3.0.3
I thought you posted you had 1.2.1?
 
This is very important, as 1.2.1 is KNOWN to have bugs with Nvidia 300.xx drivers 
Only version 3.0.3 of Precision should be used with Nvidia 306.23

Sorry no the Nvidia driver..I'm gonna just do a new install because my ish acting weird in game now? How do I go about doing a registry back-up that Sajin above recommended? Also on his step #4 it says to use CCleaner? Is that apart of driver sweeper or a different program?

 
Just slow down
Look in my Sig below, I -wrote- the Nvidia driver guide here at EVGA
And the BF3 guide as well....
 
What Nvidia driverset do you currently have installed?

Lol slow down made me giggle
I have 306.42 driver right now...I actually did read your guides but I have add and seems like a ton of things to accomplish..lol
