I managed to snag a HIS Radeon X800 XT Platinum Edition (AGP) for 17 EUR from my local classifieds. Very happy with this purchase! I temporarily put the card in this system to test it out, and it seems to be working fine. It hasn't been stored properly, so there's some minor corrosion on the VGA and DVI ports, and the cooler is somewhat dirty. Otherwise, the card is doing great. I'll post a pic in a few days when I have some time to clean it up and change the thermal paste.

A couple of observations. First, the card doesn't display anything on the DVI port during boot. Meaning, the screen simply remains black until Windows loads and the drivers kick in. In contrast, the VGA port works fine during boot time. I've googled this, and it appears to be a somewhat common issue on X800 cards. There's even a thread on this forum where someone is describing a similar problem.

Second, this card adds a new panel to the Catalyst Control Center called "Overdrive":

Never seen this before. I'm guessing it's some factory overclock thing? This card is plenty fast for Win9x even at stock clocks, so I doubt I'll be using "Overdrive", but I'm curious if other people had any experience with this feature.

I vaguely remember seeing something along the lines on a HIS X1950 Pro, and it's basically an OC feature, from the looks of it.

As for DVI: what adapter (or cable) are you using? I have a similar issue with DVI2HDMI adapters, but classic DVI2VGA will show POST fine - this happens on almost anything pre HD-series cards - 9000,9200,9550, 9600, 9700 and even my broken 9800SE AIW.

In this case, I'm using a DVI cable connected straight to the DVI port of my Samsung SyncMaster S24B420BW. This monitor has a native DVI port, no adapters needed.

I suppose I could try a few other monitors and see if it makes a difference.
