Now through Monday night is your last chance to pick up a new gaming rig from brands like Alienware, Asus, and Lenovo at the best price of the year. Don't wait, because these deals won't!

Cyber Monday is here and the deals are well underway. Retailers are offering killer discounts on everything from home-office PCs to decked-out gaming rigs and sleek all-in-ones. Still, not all computer deals are built the same.

For more than a decade, I've tested PCs and edited hundreds of reviews, so I know what's a good deal and what you should skip. These big deals from Acemagic, Acer, Apple, and Dell are worth a look.
