Would anyone explain me how I tell if a processor is good? Is it dependent of the number of cores or GHz? Is each feature especific to different tasks? If I want to run multiple programs at the same time it's better to have dual core right?
Even a single program can use many cores at once. For instance the latest games consoles have 8 cores in them- expect new games to like lots of cores! A dual core is the minimum for modern games, to be honest.
The best way to compare performance is using Anandtech's Bench tool: http://www.anandtech.com/Bench/CPU/2 You can compare lots of different CPU's performance on different benchmarks, including games. For instance, this is the comparison between a 3.6GHz Pentium 4 and a 3.3GHz Core 2 Duo: http://www.anandtech.com/bench/product/92?vs=54 There are a lot of different factors that affect CPU performance- cache sizes, instruction set support, pipeline depth, execution width, clock speed, memory bandwidth, number of cores... Trying to predict performance is nearly impossible! Comparing results on benchmarks is the only reliable way.
