Today's top deal strikes fear into the heart of videogame consoles. The small Alienware X51 gaming PC is roughly the same shape as a console but is much more powerful. The X51 is armed with an Ivy Bridge Core i5 CPU and a GeForce GT 640, and 8GB of RAM. It's running for $800 (normally $900) and comes with a $100 Dell gift card. We really liked the system and gave it a 9 in our review.
