Windows considers cpu sockets for licensing purposes only.    XP Pro is 
enabled for two sockets, while Windows Server is enabled for more.    
the NT kernel that its based on can run on up to 16 or more cpu cores, 
however it has many of the same issues with kernel resource blocking and 
such as linux, such that its a rare desktop workload which will actually 
keep 8 cores busy.

Looking at the applications the original poster gave, they are mostly 
highly interactive programs (adobe graphic software, mathematica, etc), 
I'm not sure what benefit more than 2 or maybe 4 cores would have with 
that workload.   Sure, a few filters in photoshop can take several 
seconds to run on large prepress jobs, and if you're a really advanced 
PS user, you might actually build a complex macro stack and run it on a 
big batch of pictures in the background, that might tie up a couple CPUs 
for the several minutes it takes to run...    Yes, I know large complex 
tasks in mathematica can run for seconds or even minutes, but most of 
the time most of that software is sitting waiting for user input.
