Should I look for some kind of graphics card to add to this old clunker, so that I can run Upscayl? Or maybe I should just try to upgrade the whole dang machine. I'm often paralysed by these kinds of decisions. 
What I do know is-- looking back through a lot of the image work I've done the past couple years, so much of it looks mediocre to me, and probably not worth using without additional work.
It's not like image enhancing software is the only factor here, still it's a critical part of the process, and I've come to realise that my current tools are borderline obsolete. (not GIMP, which is still awesome)
Mr-Do from the MAME scene was saying that most good MAME artwork starts at... I guess it's like 600dpi or so. Right now the stuff I'm working on is ~half that. So, right now, even if I do produce something the community can use, people might just say 'that's crap, we need better.'
Bah.
Thanks for listening to my bitching & moaning, assuming anyone did.
