I need a laptop I can use for school and I would like to be able to play some games on it while being portable. I am willing to spend $800. I need atleast 8 gbs of ram and a decent processor.
DDR3 Terrible, NO! It's practically standard for GPUs on all but the most modern laptops.
For $800, there are few even half-decent choices. The Lenovo Y50 and 510 being two other choices at that price point. You might be able to find a refurbished near $1000 machine at that price instead.
