I'm looking to buy a gaming laptop, but I don't have much of an idea where to start looking as far as brands and spec. Any ideas? Is the graphics card the most important feature for gaming? Which graphics card should I look for? Sorry if this question seems vague, but I just don't have much of an idea when it comes to what specs, graphics card, etc I should get for a gaming laptop.
Edit: This is the first laptop that caught my eye at Microcenter.
