only thing close to that price and being able to game is the lenevo y410. I think its usually on sale for around $800, and is the only system that low that will offer a dedicated graphics card that is going to handle any kind of good gaming other than facebook stuff. Otherwise gaming laptops are $1200-3000.
What you want it for, and what you want it to do, require good parts. Not going to find those cheap. Good laptops for editing 'start' around $2000. Decent laptops that will give you medium settings for gameplay usually 'start' around $1000. The lenevo is the only one i know of that goes for less than a grand. And its still decent, but you get what you pay for. You'll get a 14" 720p screen, i5-i7 , poor battery life, will run warm and loud when under stress, and chasis wont feel rock solid. But for under $1000 thats the best option.
