Your questions are irrelevant at the moment - we'll discuss them later after you have a successful, fresh installation of 10.10.1 using HD4600, and then following my procedure in Post #1 to install your GTX 750 Ti.
FRESH INSTALL RESULTS
Part 1: The HD 4600
Stork, I did everything as per your first guide to get the HD 4600 working, EACH AND EVERY SINGLE STEP:
http://www.tonymacx86.com/yosemite-...600-chimera-multibeast-method.html#post925481
The install went through smoothly without any Kernel Panics at all.
It worked perfectly on first boot too. The system booted up with full acceleration QE/CI on the HD 4600 (OS X detected the card and the VRAM correctly, loaded everything and all). Except for some slight graphical choppiness while transitioning from the login screen to the desktop, everything else was fine. I even had transparency on the menu bar, side bar etc. At this point I didn't require any bootflags and I had only the Macintosh HD plugged in.
Part 2: THE GTX 750 Ti
Trouble started when I installed the ASUS GTX 750 Ti PH 2GB DDR5 and the latest Web Drivers exactly as per the steps detailed in http://www.tonymacx86.com/graphics/...am-new-gigabyte-750-ti-2gb-graphics-card.html
The only positive difference this time compared to my previous attempts was that when I opened NVIDIA Driver Manager in System Preferences, the ECC tab showed that my GTX 750 Ti was connected although ECC was unsupported for it (this even when I wasn't using the GTX 750 Ti and booted up with my on-board graphics. I had to do so because the GTX 750 Ti would result in absent HDMI output as you'll see me mention below, so booting with on-board graphics was my only option). In all my previous attempts, the ECC tab used to show all slots as empty.
Now, more about the problem I'm facing - Everytime I boot up with the HDMI cable connected to the GTX 750 Ti and nvda_drv=1, my screen goes black after the Apple boot logo - no HDMI output it says. This is a problem that existed even before and it is not going away. This is the same problem that a lot of people with Gigabyte and ASUS cards for the GTX 750 Ti are complaining about. Only the Palit cards seem to be giving no trouble at all. You are one of the few who has managed to get the Gigabyte card working.
Part 3: GIVING UP ON THE 750 Ti and just wanting to boot normally with the HD 4600
Frustrated with all these attempts to get the 750 Ti working, I decided to plug in all my other drives (so that I could boot into Windows 8.1) and connect to the on-board graphics.
However, after this, Yosemite started getting stuck during boot - verbose boot initially indicated something related to the NTFS drives that I had just plugged in, then related to the Bluetooth Controller and finally a bug in process suhelperd. Keeps cycling between these randomly although the NTFS issue seems to have largely disappeared after I booted once into Windows 8.1.
Right now even with Init Graphics in BIOS pointing to IGFX and with Intel Graphics enabled in it, the only way I'm able to boot into OS X is in Safe Mode and with nvda_drv=0 (obviously) which is a completely sucky, laggy experience. I'm not able to boot in normal mode even with the HD 4600 which I initially was able to do. 'About This Mac' isn't detecting any card, all it shows is 3 MB worth of Graphics.
CONCLUSION
I'm completely lost as to what is going wrong with my Hackintosh. Why am I not able to get the 750 Ti running like you? I followed each and every step you mentioned in the guides. Do you think it is an issue with the ASUS card and that I'll never ever be able to get it running with Hackintosh?
Also, how do I fix my Hackintosh for now and get it booting normally at least with the HD 4600?
