Thanks to your amazing support and generosity I was able to upgrade my 6 years old PC config and according to Blender's official benchmark it's a HUUUUGE improvment *-* !

So what does that mean?
Short version:
Easier animation, faster render, improved visual quality, more physics/simulations.

Long version:
- Blender is faster so it's easier and more pleasant for me to work -> faster and better animation.
- It also allows me to add more complexity to the scenes without it being too slow or crashing so probably more physics/simulations or other computing-hungry things.
- I already experienced render times divided by 2 to 3 times with the rendering method I use (Eevee).
- But the big difference should be with the advanced ray tracing rendering method "Cycles". I've never used it because every frame was taking forever but now It may be worth it.
- And this is a maybe but it could help a lot in the adaptation of my videos to VR.

So again thanks a lot for every people who made that possible <3!
I'll continue to work hard, try to learn and improve my creations always more ^^.

Take care ;) .
