Stuck on black apple screen after sierra install!

Hey all, i built my first "hackintosh" back in 2012 and it has served me well in the past 5 years or so, but being stuck on an older OS has started to hold me back from using newer programs and hardware that i own, so upgrade it is!

Now it's been quite some time since i have last done this and all was going well. Sierra installed with no issues and i ran the multibeast set up... now when i restart and attempt to boot into Sierra i'm met with a black screen with a white apple logo and a loading bar that wont run.

My config; GA-Z68X-UD3H-B3 (legacy bios) Intel i7-2700k (Sandy Bridge) EVGA GTX 660 FTW 16GB Kingston ram (4x 4gb sticks) 60GB SSD (boot drive) & 2TBHDD

It is my suspicion that it may be related to the graphics card, as i believe that may have been the problem during my first install many years ago. I have spent the last few hours following suggestions on older threads to no avail, so my last option was to post here. I have posted my Verbose log below if there is any information you may need i will be pleased to provide it for you. Thank you in advance and i hope we can get this running together!
