We tried V6 today on a single processor 2.4 gHz with 512 RAM, XP Pro SP1 and Medea RAID 5 storage. It seems to operate a bit slower than V5 or V4 --do we need more horsepower to run it? It sure doesn't humn along like V5, that's for sure. Other than that, the GUI is nice and I am sure it will turn out to be a great tool, once 6b is released. The editor went back to V5b due to the perceived slowness. Maybe imaginary, maybe not, don't know. In any case, better than PPro!
