depends on the type the i3 has 2 cores (and 2 virtual ones because of hyperthreading)the i5 has 4 cores the i7 has 4 cores(+4 virtual ones)

cores doesn't matter in windows 7. It needs 1ghz or higher processpr to run.
The K super computer has between 64 000 and 128 000 cores.
Dual cores, though no longer cutting edge, are certainly not out of date in this day and age. Many new computers still use dual cores for their processors.
