I am not sure to understand the question. If you ask an advice about Vue 5 on a single-processor system that has similar specs to those you described, I can tell you that it runs smoothly with regards to OpenGL and it renders faster than 4 provided that you compare modes that are similar, for instance, a GI render runs faster, for me, (not to mention much better) than the tipical Ultra mode of Vue 4. So the quality renders are faster and better. The final mode of Vue 5 is comparable in render time to that of Vue 4 (some say slightly slower, not for me though), but the quality of Final mode in Vue 5 appear to be better (to me) than that of Vue 4 final. If you instead are asking how Vue 5 works with a double-processor computer, I can not answer.
