Wondering what to get

I'm wondering what I should get for my next rig. I've been sporting an Alienware M17xR1 with SLI that I've had for 6+ years, and I really need to get it replaced with something similar that will provide me the same type of excitement and enjoyment that my current system has. I'm open to pretty much anything that you guys can recommend, and something that will work with little fuss right out of the box.
