Well, I got an RMA from OcUK and also asked about what tests they do so I can at least run them myself and know I'm not mad before they send the card back to me saying all is well. Well, it turns out 3DMark06 is on the list, so I thought I'd better run mine through and see what comes out before I send it off.
To my irritation, the first run goes through fine - in fact, the ORB returns it #1 out of comparable systems, which is nice.
Thought "oh great, I've found something it does do well" and decided to sling it through the demo - got about 5 minutes into Proxycon (sic) and yep, there's the chessboard. Had to exit out, as I didn't know how to take screens. One reset, research and restart of 3dMark later and it flies straight through the first test. So we're looking good - give me some of those fairies...
Ahh, now something seems to be a bit off here. It had managed about 15 seconds of this test up to now. I can just make out the tree tump in the top-middle-right triangle, but it's all downhill from here.
CPU test 1 - not exactly going well.
This is my favourite - it's the canyon scene, although this time shown in the style of Global Technicolour. Funky.
This is the snow scene (Deep Freeze?). No, honest, it is.
The black squares are present on the loading screens, but aside from that, the bitmap is fine. The tests complete and I can just make out that ORB says my results are invalid. One restart later and all is fine - I watch three episodes of Heroes from a 1080i rip, set the machine encoding some XviD overnight and it's still smiling in the morning.
I guess I'm really just sticking these on here for posterity, and because I'm reading more stories of problems with these cards. I had vowed not to buy ATi again (my 9600pro was a smashing performer, but suffered from irritating polygon tearing in one or two games, and I'd rather be supporting nVidia, who at least seem to take Linux seriously) but the price/performance of this AGP board swayed me back. Oops.
Card will be on it's way to OcUK tomorrow - I'll post the results.

PS. I've put the full screenshots up
here if anyone wants them.
