AMD and Intel

Hello i've been thinking about buying a new PC but i do not know which CPU i should buy u usually play games but i like to work with gfx software like photoshop cinema 4D that stuff.

and i have seen here a post about CPU's performance for gaming where AMD is in the 2nd position and intel's are higher, i wanted to know if an AMD FX 8320 3.5GHz 16MB BOX SKAM3+ is good for "multi-tasking" because as i said i like to play video games and work with that kind of software.

Also i am thinking of overclocking my CPU will that push it up to a 1st position
