Why do you call the Nvida chipset "crappy"? I assume you don't care about the PCI Express bandwidth of the accompanying "northbridge"? >From a performance standpoint, the Nvida chipset is far from crappy, and can easily sustain 10GbE speeds for both send and receive, as well as send+receive at the same time. Our lab tests have shown well over 18Gb/s for send+receive using our PCI-e x8 10GbE card in an Nvidia CK804 based opteron. For any application which is moving a lot of data using PCI-e cards on an opteron, I would strongly recommend Nvidia based servers. Drew
