New Radeon 9200
Having sorted out my power supply I got around to purchasing a new videocard to replace my misbehaving Geforce 256. After much consideration I decided upon a Gigabyte Radeon 9200 for $AU105. I wanted something that was at least twice the speed of my 4 year old card, but for about $100. This was the only option available locally. For 30% more I could have got an Nvidia 5200, but the model I wanted was not being sold by anyone I'd heard of.
Although Gigabyte claimed the bus was AGP 8x/4x, I knew from my research that it would work just fine at AGP 1x. And so it was. The only problem is that it crashes when I do certain 3dMark01 tests. I tried it in a spare Celery 300 at AGP 1x, and it worked fine in that, so I guess it's my motherboard. I'll try fiddling, but I don't think it's a big deal. The games I have tested so far work fine.
