If you have a dual core 2Ghz processor does that mean windows can clog up one core and you can run games a 2ghz on the other core?
Yes, that is the reason I got a dual-core processor, although I got much more than windows clogging up the other core.
If it is worth it as a gamer is a much harder and more speculative question.
