My biggest scene in polys with Vue 4 (on the same machine, but with less memory) was 230 million - no probs at all with that. In MB it was >500 - slow, but no problems either. Haven't tested my limits, but it's definitely not as good with Vue 5 - even when using wireframe. Usually, I don't have any issue with the graphics card with any other applications, so I'll give it a bonus in trustworthiness for now :-)
