The S2891 uses the AMD8131 with the nForce Pro 2200. The nForce Pro 2200 provides the legacy PC, along with PCIe and newer features. The nForce Pro 2050 just adds additional PCIe channels and new features. Robert <roberth at abbacomm.net> wrote: > other specs in that box? > is it a screamer? Anything with an AMD8131 will get you excellent server performance, because it's a dual PCI-X 1.0 channel solution. Some HP and Sun servers use 2, and one Sun product even uses 3 (for 6 PCI-X 1.0 channels). > benchmarks? For what? The CPUs? The PCI-X I/O? The PCIe channels? You have to give some context of what you'd use on the board. Otherwise the benchmarks will vary _widely_. ;-> If you're only going to use the PCI-X channels, then it really matters little what mainboard you use -- as long as it has an AMD8131 (or the newer AMD8132 -- which is a dual PCI-X 2.0). -- Bryan J.
