MSI K8N Diamond Plus Motherboard
 

The K8N Diamond Plus motherboard uses the nForce 4 SLI x16 chipset, the newest beast from nVidia. This chipset gives you a total of 32 PCI Express lanes for graphics cards alone; this means you get full speed PCI Express x16 slots. MSI uses a small interconnected heatpipe and fan design to keep the two chipsets as cool as possible - and this is especially great news for end-users who like to build quiet computers. That’s right - nForce 4 SLI x16 is a two chip solutions. nVidia worked this by placing the extra 16 lanes on the Southbridge chipset and uses a 1600Mhz Hyper Transport link to connect the Northbridge to the Southbridge.
