New chip is it that bad?

Hi there guys I just build I computer for my little sister who mainly plays minecraft, lego games and more.

Specs:
Intel g3258 with stock cooler
Asus Z97M plus
8gb cortsair vengance pro 2x4gb 1600mhz
gtx 960 4gb strix
PSU EVGA G2 550w (I know it's a over kill but I will be upgrading cpu later down a line to I5 and also I wanted to get quality power supply so system can be upgraded in the future as quality psu usually last very long time plus this one has 7 yrs warranty)

I just had some time yesterday to overclock cpu and I only manage to get 4.0ghz @1.1v with temps of 69 on hottest core on OCCT with linpack with AVX instructions (I run it for 1h). Then I let my sister play games on it and no crash for so far.

I have no idea if this is good as never have overclocked due core as I own I7 4770k that runs stable 4.5ghz @1.265v.

I wanted to reduce render times as she likes to record videos on youtube and when overclocked a little it performs better while rendering video. Although it still takes a while to render a video roughly 25-30 minutes for 10-15 minutes video.
