Best combo for super ultra wide gaming on a laptop

Hello,

So I plan to have a setup with super ultra wide gaming monitor and a gaming laptop for portability. Even if it is a super heavy desktop replacement one, I don't mind.

So something like an MSI titan with a 5090 along with a super ultra wide or even an ultra wide.

My question is, would it even be playable?

I know that laptops can't compare to desktops and all the ultra wide gaming videos I found were with a pc connected rather than a laptop.

And ultra wide is more demanding. Can a laptop handle it even if it is a desktop replacement with a 5090?
