The high end HBA have better CPU / silicon and faster drivers, in the same way that different graphics cards have different levels of performance. The concern with storage (as a whole) is that you need to design for peak load. Hopefully someone with more knowledge of the server will post some information.

To my knowledge most intel server PCIe 1GE and 10GE adapters have a TOE onboard anyway...(not the desktop ones though) and they even support booting if you flash a different firmware! How much difference in throughput and CPU utilization are we really talking about? Any time i tested the difference was not the extra money for the iSCSI HBAs...
