Of course, since the HT1 only allowed for 4GB/s bandwidth, and a PCIe 2.0 x16 slot can handle 8GB/s on its own (don't forget that the southbridge, and therefore all storage and peripherals, also conmmunicate with the CPU over the HT link), it is possible that the HT1 link *could* bottleneck the system in general if its getting a heavy pounding...
