You often read that people do not really need more cores because the existing software hardly makes use of those extra cores. While this is increasingly not true in itself, it is absolutely untrue in BOINC, where every core counts. I will show you some scores for octo-core Bulldozers and Piledrivers, compared against hexa- and quad-core Phenom II's and a quad-core Athlon that most of you will still be using.
As with the quads I will break it up into project categories, starting with the Astrophysical ones (A. Because the 'A' comes first in the alphabet and B. Because WuProp has these values complete, unlike some other categories).
Two first value is the maximum per core per day, the next is the value per CPU per day, multiplying the scores with 8 for octos, 6 for hexas and 4 for quads.
