We have 2 G965 machines and 7 r200 machines, and they all crash. The r200 bug has been well known for 2-3 years and many others have reported it (it involves the X server spinning the CPU with a particular set of ioctls, it's pretty easy to recognize). It happens much more often when there are 2 DRI apps running simultaneously. I have an r200 at home that I've never seen crash, but I hardly ever use DRI there.

The G965 machines crash 3-5 times/day on occasion when somebody is really using the 3D hard. I've seen several reports of this same crash from others as well (it emits a DRI error before hanging, so it's also pretty easy to spot). I have higher hopes for this to get fixed in the future, G965 is still pretty new. I doubt the r200 crash will ever be fixed at this point, it's probably a hardware bug that ATI isn't disclosing the workaround for.

A lot of the r200 crashes were AGP bugs that the open source world never found about it.. so r200 in Intel AGP might be fine, stick it in via or amd and it sucks..

00:01.0 PCI bridge: VIA Technologies, Inc. VT8366/A/7 [Apollo KT266/A/333
AGP]

So it's not just that VIA sucks (although this VIA-based Athlon 4 system
has been persistently prone to spontaneous lockups and is terribly
overheating-sensitive: CPU temp above about 50C means a lockup, so it
needs a hugely overspecced fan. Perhaps I should underclock it.)

If you have the space for it I suggest taking a look at the massive scythe ninja heatsink.
http://www.silentpcreview.com/article251-page1.html

These things were originally designed for passive cooling and are just very massive. Suprisingly they aren't not heavy, you don't have to worry about the weight of the thing tweaking heatsink mounts or anything like that.

I have one on my 2.8ghz dual core Pentium-D proccessor. Pentium-Ds are infamous for being a very hot CPU, essentially being 2 Pentium4 cores.

I made a small duct for it out of stiff paper going back to the rear exhaust fan, which is a 800rpm 120mm fan. Then directly above the cpu I have the intake for the powersupply, which is another slow 120mm fan.

Those two fans are the only fans on my system and they keep my cpu ticking at barely above room tempurature. It's just amazing how efficient these heatpipe heatsinks can be.

The only serious problem is that you need to make sure that adiquate cooling is aviable for the big power conditioners/transistors typically found close to the cpu socket. If you overclock these will get very hot without air directly blowing down on them like you find a traditional cpu heatsink. Small aluminum heatsinks with thermal epoxy are more then adiquate to take care of that.

but I don't overclock so it's a non-issue.

that's another thing I like a lot about the onboard video: No need for a VGA card fan. This does wonders for making things quieter.

My old Dell 600mhz firewall hidden in the closet makes more noise through the door then my desktop currently does when running full-tilt.

Those are the symptoms of a GPU lockup, which can be caused by a lot of different things.
