<human>: Could you distill the essence of the text into 1-3 sentences?

So I have finally decided to get myself a decent quality laptop that can play all the games I want to play, but not be all too expensive. I have already browsed and found a few I want but I came across what appears to be an issue. I was looking up some of the graphics cards that come in these laptops and none of them have dedicated memory on them. For games like SWTOR it recommends a certain of dedicated memory on the graphics card. Is this something I really have to worry about, or am I just being retarted? Keep in mind, I don't want amazing super graphics, I just want to play the game.
<bot>: I am computer illiterate and need to know if having no dedicated memory on a laptop graphics card will screw me over forever.
