As matter of interest, do these cards offer lower throughput than 4x single 1GB cards?
Depends mostly on if you are using PCI/PCI-X vs PCI-express. At high bit rates you can saturate the old PCI bus. A single gigabit port can pretty much saturate a 32-bit PCI bus at 33MHz.
PCI-express can go a lot faster.

And on current multi CPU / multi core plattforms care to have support for MSI-X on the motherboard and by the Ethernet controller (for 10Gbe and virtualization this is even a must to gain maximum performance).
