iMac 11,1 - dead graphics?

Ok, this is OCLP ‘adjacent’!

Am trying to strategize my OCLP upgrade on this machine , but can you guys help me with some advice? Because I think I have a bigger underlying problem first…

Graphics has recently developed 5 vertical ‘stripes’ - about 25 pixels each… OS Catalina will boot all the way to desktop in Safe Mode…

However, in ‘normal’ boot, it progresses almost completely - with those stripes - then stops at the White Screen of Death, with NO stripes…

Does it seem clear I have a dying graphics card? Reading up on Ausdauersportler’s GitHub work; anybody want to offer some specific advice ??
