I have the option of 3.33 ghz 4 core processor, a 2.66ghz 6 core or a 2.93 ghz 6 core.
I know that the middle one will be slower than the last, you don't have to tell me that.
What I would like to know is what would work better? 4 fast cores or 6 slower ones? I know that if you do the math the last one is the best but how many cores can Blender use?
I would also like to know what would be the best for blender internal renderer and cycles (if there's any difference.)
