I know that there was the announcement that the rendering task has been shifted to another core, but AFAIK there was no specific core assignment given.

If your example would be true, then my second core should boil (because it would have to handle CloD and its rendering task) but it doesn't. This would also mean that my OS uses 55% of core #1 while running CloD - which seems not to be reasonable - because nothing else runs in the background (except for the Steam client).
So from my current point of view, core #1 is occupied by OS and CloD, core #2 is occupied by the rendering task and from that understanding, I can't see any benefit by using a Quad-Cpu.

What do you think?

I'm no programmer so can only repeat what I've read here in the forum...and that is that in one of the patches you can set so that CloD will use one core for rendering textures only.
According to the patch readme this is supposed to give a performance boost to quads (over duals). If this is true I don't know.
As you say CloD doesn't use resources efficiantly today so I agree with what you're saying but perhaps CloD will utilize the cores differently and more efficiently in the future...hopefully.

I don't think there is a problem with unbalanced loads (because both cores run on ~55% during CloD), my question was if it would make sense to add another two physical cores ;)

Luckily, I got my hands on an i7-870 (4x2.93GHz), so I (and you) will have an answer soon :grin:
