^ +1 A dual core is just two processors running at 2.33GHz, and a quad core is 4 of them at the same speed. If an app you are using is single threaded only, it will only use a single core, so the program would perform just like a single core 2.33GHz processor. Everything beyond that depends on the optimization of the software, and its requirements. Quad cores make a huge difference where multitasking and multithreaded apps are concerned. I would completely ignore the "Can you run it?" score, it doesn't make sense to take additional cores and model them as additional GHz with the way processors are today.
