A few days ago I ordered an ATi Video Card, a X800GTO (AGP port because that’s all my motherboard has). Received it today and installed it. Had fun when I tried to boot up Ubuntu, and the graphics system x.org threw a hissy fit because something had changed, and threw me into command line mode. Not even able to load a website to figure out how to fix it, I had to run off to uni. Eventually got it working, and I think it’s working fully now. At least, I hope so.
So Technically, I have upgraded my computer. Consider goal Achieved.
