Gaming and Grafix PC build

hello guys a friend of mine told me about this forum, which is great by the way, as i am looking for a low budget pc that can handle games in medium-high quality settings and grafix software like photoshop and cinema 4d.

Approximate Purchase Date: I don't have any purchase date

Budget Range: Between 500-650 (Euros)
System Usage from Most to Least Important: Gaming and grafix, watching movies etc
Are you buying a monitor: No

Do you need to buy OS: No

Preferred Website(s) for Parts: it is a Portuguese site it's called www.chiptec.net

Parts Preferences: I would like to buy a AMD CPU

Overclocking: Yes
SLI or Crossfire: I do not know what is SLI or Crossfire

Your Monitor Resolution: 1920x1080
Additional Comments: i would like to request a build for a computer that doesn't make much noise, although i need it to be capable of playing most new games in medium, if possible with this budget.

And Most Importantly, Why Are You Upgrading: My old computer is getting old and therefore it hasn't been able to run most of new games in low quality settings and one of my hobbies is working with grafix software like photoshop and cinema 4d
