Lo and behold, it works!
I posted this eariler today:

and have managed to install the card with the latest drivers. Mind you, I have not optimized anything yet, still learning, but from what I can see, everything is working as it is supposed to, (never mind the Windlight bugs)
There really is hope for us with older pc's.
A couple of screenshots from my balcony, nothing special, but just showing that it works!

(the card was US$52.99 on sale, older hardware, so not many left out there)
/yrrek wonders if there might be a commission involved?
