Question: is 1.6 ghz quad core good?
Answer: Dual-Core, good for light task loads, such as general home computing, light games, and movies. Quad-Core, sweet spot for gaming as modern games prefer having 4 cores, but don't have a use for more. Octo-Core, these can game as well, but having eight cores means that most games will only make use of 4 of them.
