1 little, 2 little, 4 little CPU cores?

[Hedge-o-Matic]

IBM and Intel already have loads of cores on a processor. It far exceeds 64.

As for the average (well sort of) consumer, in a few weeks/months Intel's quad core xeon processors will be put into workstations. Of course, being Xeons, they can run along side each other so you'll get 8 cores to play with. Most people won't need all of those...I will for video and audio editing. I already take up close to 400% CPU usage while encoding video. The more cores, the better

If you were to theoretically, have 8 cores worht of Xeons to use, would an application be able to access the power, or would code need to be specially optimized for x-cores? Since I do a ton of rendering and 3D work, this would be really useful, obviously, but will 2k7 be able to use this processor capacity?
