Introduction

I built Hector with adding the Gigabyte 750 Ti graphics card in mind. However, at the time, Mavericks did not support the nVidia 750 Maxwell chip graphics cards, and Yosemite had yet to be released. So, I struggled through getting Mavericks installed using the on-board graphics and the new i5-4690 Haswell Refresh processor (gave new meaning to the term "early adopter"). Now, with nVidia's drivers supporting Yosemite/El Capitan/Sierra, adding the 750 Ti is possible.


Amazon || Newegg
Out of Stock - GTX 950 Replaced the 750 Ti > Amazon || Newegg
Note: The above Gigabyte GV-N75TWF2OC-2GI is now out of production and has been replaced by the GV-N75TOC-2GI at Amazon; Newegg has the GV-N75TWF2BK-2GI. The Amazon and Newegg links have been updated to reflect the respective models. However, the benchmarks below reflect the original Gigabyte GV-N75TWF2OC-2GI.



Why did I choose the Gigabyte 750 Ti? I needed a 750 Ti graphics card with at least two DVI connectors to drive my two monitors (Dell U2711 2560x1440 & HP ZR24W 1920x1200) which are shared among four systems by the IOGear 4-Port Dual View Dual-Link DVI KVM switch (GCS1644). I also like the low power requirement of the 750 series graphics cards - only a 400W PSU required and 60 W of heat is easier to dissipate in the BitFenix Prodigy case.

This card should be good enough for my game playing which I've just started again after a long hiatus from playing computer games. Finally, an unforeseen benefit of the Gigabyte design is that it also comes with two HDMI connectors and is advertised as being able to drive four monitors. For more information, see Gigabyte's web page in the References below.

I'm now running Sierra on Hector using nVidia's web drivers as Apple doesn't support the 750 Ti without the nVidia drivers.


Benchmarks

Here's some benchmarks with Sierra (10.12) that I'm going to use in Hector's User Build description update.

Installation

Below are the installation instructions for initially installing the nVidia Web Driver.

High Sierra Initial Installation Notes with the GTX 750 Installed

:ch: I use the MultiBeast default System Definition, iMac14,2. The other, more "modern" SysDefs are filled with problems which, IMO, are not all that beneficial.
:ch: I do not recommend installing or upgrading to Mojave - Nvidia has yet to release drivers for the GTX 750 Ti in Mojave. Additionally, wait until 10.14.3 is released. Mojave 10.14.1 has bugs.
:ch: Install High Sierra per the tonymacx86 High Sierra installation guide (review this guide before reading the rest of this procedure).
:ch: After the second part of the installation is complete, run MultiBeast, select your configuration based upon your motherboards drivers, etc., and these two options:
Bootloaders > Clover UEFI Boot Mode + Emulated NVRAM<--- Page 6, MultiBeast Features document
Customize > NVIDIA Web Drivers Boot Flag <--- See page 8, MultiBeast Features document.​
Complete the MultiBeast installation, but don't reboot.
:ch: Now, run the latest nVidia High Sierra 10.13.6 (build 17G3025) web driver (387.10.10.10.40.108). See also NVIDIA Releases Alternate Graphics Drivers for macOS High Sierra 10.13.6 (387.10.10.10.40).
:ch: Reboot.
:ch: If your "use Nvidia drivers" doesn't stick and you don't get acceleration, then you'll need to install the Clover EmuVariableUefi-64.efi. There are two ways to install the EmuVariableUefi-64.efi:
:ch: Easiest way is to run MultiBeast and just choose the option below and install/reboot:
Bootloaders > Clover UEFI Boot Mode + Emulated NVRAM <--- Page 6, MultiBeast Features document​
:ch: See Problem 6 in slim.jim's excellent trouble shooting guide, the Solving NVIDIA Driver Install & Loading Problems.​


*Note: Although I try to keep this link up to date, this may not be the latest driver.

Yosemite 10.10.1 cured a lot of bugs (more bug fixes yet to come, though). If you use the latest nVidia web drivers, you shouldn't have a problem as I indicated in my Post #1. But, I had my system running w/o a graphics card first. To your question, I don't see why your ASUS GTX 750 Ti shouldn't work.

BTW, to test Gigabyte's claim, I've got 4 monitors working with my setup - 2-DVI & 2-HDMI.

I'm not telepathic. I don't know why you can't get the HDMI to work.

Did you install Yo using your on-board HD4600 first? Did you use the procedure that I did in my OP? Have you installed 10.10.1 and the latest nVidia drivers as I pointed out in my OP?

Stork, are you getting native power management using the web drivers? I'm not getting any clocking down (I am using the drivers) and I also have 0 MB VRAM shown in About this Mac. However, this is only a cosmetic issue as I am getting full QE/CI acceleration.

I've also patched my AGPM.kext to get rid of the AGPM unknown platform error but I'm still not getting any native power management. Any ideas? Thanks.

I have attached my patched kext below.

PM is not included with the web drivers. At this time, there is no native OS X AGPM support for Maxwell.
