Graphic card upgrade for Acer Predator? (1660S)

Hello, it depens entirely on the usage.
What resolution is the screen they are playing on (1080p, 1440p?), what games do they play and do they eg. prefer lower quality but more fps or want highest quality? Plus obviously budget, looking for some 2000sek used card or can spend 8000kr on something new?

What is also important for what fits in the pc is the size of the chassis, as some models of higher end gpus can be too large. As well as what PSU the pc has, as that is a limitation of how many watts the gpu can draw.

looks like it is pretty standard PC component except the motherboard which you don't wanna mess with

So it the comes down to the PSU and what the wattage is.
I would guess a 4060 could do fine as long as it has 1 8 pin power connector.

And, the card can't be too long.

says 500 watt PSU, so you are a little bound by that.

EDIT: both PSU and motherboard seems like proprietary stuff...but if you just want to replace GPU then that is totally doable. Make sure it fits, and that it is not too power hungry. It does have atleast 1x8 pin connector for power.
