FSX: Building mini-cockpit set up which CPU, GPU, and Mobo would be best?

Hello,

I am currently planning to enhance my FSX experience in a custom-built PC (homemade off course) and what I am thinking is a multi monitor set up with 3 1080p computer displays, with a joke, pedals, throttle quadrant, comm stack, and maybe one additional LCD display for instrumentation purposes.

This is off course a rough draft because I am wondering what hardware selection would be best for this type of mini-cockpit set up. My budget is quite flexible but moderate.

In that sense, this is the type of components that I am thinking in terms of hardware & software...

1. 8GB RAM DDR3 1833MHz
2. 3 1080p Displays + 1 display for instrument purposes.
3. Saitek Pro Flight Joke + Throttle Quadrant
4. Saitek Pro Flight Pedals with Toe Braking
5. Saitek Pro Flight Comm Stack
6. TrackIR
7. 2 HDDs; 1TB for Windows OS (not sure whether to go 7 or 8) and 320GB for FSX.
8. Microsoft Flight Simulator X Gold Edition SP2.
9. 750W Power Supply

These are the unknowns where I would gladly accept suggestions for hardware given my set up...

• Currently thinking of using a Haswell Motherboard (thinking of this candidate from GIGABYTE) and using the Core i7 4770k or Core i5 4670k. One last thought, given that we are talking about FSX, should I just go for the Core i5 4570?
• As for the GPU, I am actually unsure of which one to pick. I know that most of the agreement here at AVSIM is that the Nvidia GPU is the best one for FSX. Which Nvidia GeForce GPU do you guys recommend for a multi monitor set up for FSX? I am willing to accept an AMD wildcard suggestion because I have seen some YouTube videos showing FSX multi monitor set ups using AMD GPUs with their Eyefinity technology.

That's all for the moment and I appreciate your answers and suggestions!
