This month it was mostly price changes. Some a few dollars and some $10 and $30 changes. The only changes to the hardware in the lists was the video card and case recommendations in the $250 Upgrade and $500 Computers. An Nvidia 9500GT was replaced with a Radeon HD 5670. The cost went up about $20 but I think its worth it. The 5xxx series supports DX11 and can play all the latest games, just with all the bells and whistles turned off. The case was replaced with a very similar one only with a higher wattage PSU to allow for the updated video card.
