The intel cards that use the EM driver are the best performing cards in FreeBSD that we've tested. We've test cards made by the same company that use the broadcom controllers and the intel cards are substantially better (ie use less CPU passing the same amount of traffic). Be careful using on-board controllers. Usually vendors, for some reason, don't wire them to the pci-x bus. Most supermicro boards wire the em controllers to the 32bit/33mhz bus and the tyan and supermicro opteron boards we've tested wire the broadcoms to a shared 1x PCI-E, both of which will not only give you poor performance, but are not capable of running full gigabit rates.
