Mavericks 10.9.4 does not recognize my GPU 780 Ti

[the100yengamer]

I just build new Hackintosh with below components

CPU: Intel Core i7-4790K Processor
RAM: Crucial Ballistix Tactical Low Profile 32GB Kit (8GBx4) DDR3-1600
GPU: EVGA GeForce GTX 780 Ti, 3GB, 3072MB,GDDR5
PSU: Corsair RM Series 1000 Watt ATX/EPS 80PLUS Gold-Certified Power Supply
Mobo: Gigabyte GA-Z87X-UD5H Z87
HDD: Seagate Desktop 3 TB HDD SATA 6 Gb/s
FAN: Cooler Master Seidon 240M

Everything is working fine, except I cannot set to use my 780 Ti
No matter what I do, Hackintosh would not recognize 780 Ti

I did all the parameters like GraphicsEnable=No, and such

I did install newest Nvidia Driver and Cuba driver, Pc show successfully installed, but it just
does not want to use the 780 Ti

I currently have the 780 Ti plugged in to PCIex8 slot, does this matter?
Does this have to be plugged in to PCIex16?

Any thoughts?

I have been fighting with this issue for few days and am desperate for any help

Did you install the nVidia drivers? See the exception note in the buyer's guide graphics card section - it has a link.

Yes, I did install the driver (Newest one) I had GPU plugged in while installing the driver....is this a problem?
