As as people here probably want to play with their computers,
why buy a expensive Dual Core?
Why not get a powerful single core and use the money for some more performance somewhere else?
Currently, the most powerful and best value for money CPUs are all dual core to my knowledge and they are the Core 2 Duo / Extreme CPUs and their variants. I have heard that Intel will release a single core Core 2 based CPU in the near future, but I don't know they will for sure.
Windows XP/2K and MS office utilise dual core CPUs to improve performance. Many games do not use dual core atm, but they still benefit from dual core, in that one CPU can be dedicated to the game, whilst the other deals with background OS processes.
Dual core also means that you can run one application constantly (like folding @ home for example) whilst still being able to play games, use DTP software or surf the net without a real perceptible decrease in performance, compared to doing the same thing with single core, where the performance hit would be noticeable. Also, I've found that switching between a full 3D game and desktop (ALT+TAB) is a lot faster with dual core as well, which is a nice benefit for those of us who like to check e-mail and surf the net etc in-between rounds on AAOL
If your question was about quad core (coming very soon) I'd agree with what you question implies, as I don't personally believe quad core is worthwhile with current software, but dual core really does offer worthwhile and perceptible benefits over single core, more so than quad core does over dual core with current software, imo.
