like they say... but in a different way, the Dual Cores is more like having your 3 years old daughter cleaning the dishes with you... she do it to help you, and if she do it right, it actually help you... but most of the time, you have to do the job twice because she do not check if the plates are clean... she just put water in glasses but do not clean them... and usually, you have to clean her mess because there is water everywhere...

Dual Core and QuadCore (like i have in my computer) is the same... actually, 99% of the softwares on the market are like any daughter... they are not fit to do the job properly yet... they are to be rewritten, and most of the software developpers does not care. like your daughter does not care about what you teach her about the dishes...

because it is software related actually... Photoshop CS3 is doing it.. parts of the software are using the "split" needed to use both cores... some new games are doing it too... but not even your web-browser yet... Windows Vista is close to do it, but OS-X Leopard is full into it...

it is really hard to see any use of the Dual Core for a simple usage... very complicated softwares and extensive high-end users may have a use for it... (killing people and graphics are that kind of usages!) ... lol
