You are doing media processing. 2. You are a developer and know how to do things like parallel builds and/or write your own parallel code. 3. You are running virtual machines. The ability to use multiple cores/threads has little to do with the OS. Most "ordinary" applications still don't make good use of multiple cores. >From what you've said so far, it sounds like the number of cores you buy is just marketing hype as far as you should be concerned.
