CPU Speed vs Number of Cores?

for what your doing buy whatever is cheaper

I would agree with this, so go for the higher CPU GHZ rating for your listed applications, versus more processor cores.

Per Microsoft, all Windows 7 32 bit versions supports up to 32 processor cores. Windows 7 x64 supports up to 256 processor cores. Actually usage is going to depend on your application.

Just remember, processor cores does not mean physical processors.
