|You aren't going to have any choices in the model of the board. You have a laptop so the board is more or less dedicated to that model. If your model came with more than one series of graphics chip then you could possible which to a better graphics. I would guess that won't be the case.|
You should consider what the current value of that laptop is and not spend even that much to repair it.
Why do you keep breaking the connection? are you moving the laptop while you have AC power connected?
