Need some help with my GTX 670

Need some help with my GTX 670, Please!

Hey guys just recently i have noticed since i upgraded my GPU from a Radeon HD 6850 to an EVGA GTX 670 FTW Edition. That in OS X, starcraft 2 lags like a champ.
I have already removed all the ATI Radeon strings from boot.plist i.e AtiPorts=4, Duckweed framebuffer etc. I set it to GraphicsEnabler=No as well. Im attaching a few screen shots.

I ran LuxMark v2.1beta2 GPU benchmark, and it doesnt show the clock speed of the GFX card, i have full acceleration...and i applied the patch from multibeast 5.2.1: Drivers -> Graphics -> Nvidia Fermi -> >2GB OpenCL Patch -> 10.8.0+ OpenCL Patch

Iv also installed the latest Nvidia CUDA drivers and Official drivers from Nvidia: http://www.tonymacx86.com/257-nvidia-releases-mountain-lion-10-8-2-graphics-drivers.html

Based on my LuxMark Score, it seems like the card is working just fine? But i have set the gfx settings in starcraft 2 to medium, and it still lags pretty bad.

And i'm not sure why in system report the card shows up as a x8 PCIe Lane Width

Any Recommendations? Is there something else i need to install from multibeast? Thanks in advance.

Bump. Anyone?

x8 PCIe Lane Width:

The first x16 PCIe slot on z77 boards (and others) gets 16 lanes if it is used alone. If both x16 ports are used the lanes will be shared by x8 and x8. No matter if this second card is a graphics card or whatever.

Its important to know that not all physically x16 ports get 16 lanes. The second x16 port has the full lengh to fit any graphics card but is always only connected by x8 lanes (even if used alone). High End boards get around this by extra chips to generate more lanes.

Your motherboards handbook should make this more clear.


Edit:
Gigabyte GA-Z77MX-D3H extraction (features):
**********
Expansion Slots

1 x PCI Express x16 slot, running at x16 (PCIEX16)
* For optimum performance, if only one PCI Express graphics card is to be installed,
be sure to install it in the PCIEX16 slot.

1 x PCI Express x16 slot, running at x8 (PCIEX8)
(The PCIEX16 and PCIEX8 slots conform to PCI Express 3.0 standard.)

* The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot
is populated, the PCIEX16 slot will operate at up to x8 mode.
