IBM "If it's the number of cores that gets computers excited these days, then IBM may have its hands on the ultimate processor. Together with Rapport, a Silicon Valley startup, the company previewed the Kilocore1025, a processor with a total of 1025 cores that promises not only to boost processing speed but also to operate at low power levels."

OS is the bottleneck

In multitasking of high levels, ie, if you run at least 12 applications ( with 4 SIMDs=single instruction multiple data and with enough HDD feed) the OS not the CPU power will be the bottleneck. OS might get crashed due the amount of load and the interrupts it encounters every second. Loading and unloading applications from RAM also becomes a serious issue if the OS services doesn't guarantee it to be smooth, efficient and without residuals remaining in the RAM ( ie leaking).
Few OSs will be able to support extreme multitasking without stability issues.
