The Inq has some details about the specifications of Dell's upcoming AMD lineup:
If you thought that the AMD-ATI line-up will shove Nvidia out of the door, think again. SNAP (Strategic Nvidia-AMD Partnership) was never dead, nor will it end anytime soon, since AMD is constantly telling us that "AMD is not Intel". The Dell line-up only confirms what we previously thought. All of the business-class PCs are equipped with Nvidia nForce 430 chipset with integrated GeForce 6150 graphics. The graphics is also upgradeable since every PC comes with PCIe x16 slot built-in.
The line up is divided into Dimension, Optiplex and XPS. However, XPS will not be launched alongside the Dimension/Optiplex combination, since the company is waiting for AMD's 4x4 platform. We will give you more details about XPS line-up in a series of follow-up articles, so stay tuned to theoINQwire for more news. But you can expect that Dell and Dellienware will probably end up as the highest volume provider for the 4x4 platform.
