Is it enough for GC games ?

There is nothing you can do . It's a laptop , not a desktop which you can swap components easily . Did you think you could open/disassemble your laptop , re-soldered your CPU ?
AMD A4/6/8/10 5xxxM doesn't support overclocking and overclock a multimedia laptop = Suicide anyway
There are 2 solutions :
_Give up and save your money for later build
_Build a new gaming PC or buy a gaming laptop now
