2ni, the problems in Vue are not universal. I, for one, have very little problems with my configuration.  By the way, I already had two completely different configurations, with similar results in Vue stability (dual core 4 GB XP 32 ATI and a quadcore 8GB Vista 64 Nvidia, later changed to ATI).

My Vue always ran perfectly in my ATI's. I never cared about drivers of any kind in any of the machines, I have no idea if I have the latest or not (probably not).
Although I removed all programs from background (like widgets, accelerators for QuickTime and other similar stuff, real time spyware scan, etc) it's common for me to run Vue simultaneously with several other apps, like Poser, Photoshop, Zbrush, etc, and I never noticed any problem because of that. Only for render time I let Vue run alone, mainly for speed reasons.
In average, I have a crash every 20 hours of work (for me, that's once a week), when the scenes are starting to get really heavy. This doesn't bother me much. Of course I would prefer never to crash but I can live with this.

I would still say the problems out there can't be all due to Vue. Or I (and others) would feel it too. There must be something else too. It can't be the configuration alone. I would say it must be the combination of several things.
