I am just kind of curious

So the picture is a steam deck spec's if u are curious. So I been thinking about getting something so I can play games like spiderman and cyberpunk and horizon 1 and 2 and red dead redemption 2. My friend she has a steam deck and she tells me it is a good little system but it is under power. Like horizon forbidden West she has to lower the graphics a lot to get the game to play well. i kind of like those tiny PCs they are small and won't take up a lot of room. If I got one and upgraded the ram to like 32 or 64 would it play a lot better. She is all was complaining about the storage with her steam deck. I would upgrade that also.
