is a 3.20ghz processor good ?

Solution
Very likely you will find it to be 'lacking' by todays standards, aim for a quad core or more if your benchmark is modern games.
Depending on the architecture behind it.

Raw speed isn't the biggest factor here when it comes how well your CPU performs.

CPU's from almost 10 years ago were capable of hitting about 3.0Ghz, does not mean they are still capable of modern games.
 


it's an intel pentium dual core
