Key differences between the base model G3-571-77QK and the 300$ older brother G3-572-72YF?

I did some reasearch and found out that the upper version gets the original Metal AeroBlade fan over the plastic ones, and we also get a 1TB HDD with 72YF.
What else ?
What else makes it cost 300$ extra?
I'm not quite sure about this but I read it on some post online that the base version doesn't allow overclocking the gpu.
Is it true>?

You have the right information. G3-572 has metal fans and supports gpu overclocking, unlike G3-571.

So I followed this post (acer-predator-helios-300-g3-571-overclocking), what's the verdict?
Should I prefer the base model and hope that I figure out some way to overclock it?
This would be my first gaming laptop,
The laptop I own supports overclocking with the AMD overdrive set.
Or suggest me another laptop in this range.
If I'm paying the extra 300 bucks, should I go with

Eluktronics P650HP6 ?

Maybe try Lenovo Legion y720-15. I don't think that overclocking method for Helios G3-571 will be discovered.  You have to edit bios but it will probably make G3-571 very expensive brick.
