Dell Home, via its Member Purchase Program, offers its Dell Alienware Graphics Amplifier, model no. 8W39R, for $161.49 with free shipping. That's $39 off list and the lowest total price we could find. (We did see it for $189.99 bundled with a $50 Dell gift card three weeks ago.) This external graphics card slot upgrades an Alienware 13 laptop to support full-length, double-wide desktop graphics cards. It features 460 watts of dedicated graphics power and a powered 4-port USB 3.0 hub. Deal ends May 26 at 8 am ET.

Note: A graphics card is not included; you must supply your own. Dell's MPP is available to select groups, including students, government employees, military (active and retired), credit union members, and health care workers.
