@d1stortion, it was mentioned in their faq section actually. My bad, if my post was ambiguous.
@swaaye, I think pci bus performance in general should be ok, though I may be dead wrong. probably it's more about the efficiency of the data transfers between the gpu to processor/memory via the reverse & host bridge. The closest I got to measure that was through Final reality bus transfer rate tests for 2d & 3d which seemed abnormally low to me. Or maybe the bus transfers are frequently getting interrupted resulting in poor efficiency. Changing the latency timer of host bridge affects the performance in both ways whereas changing it in the reverse bridge does nothing, which I don't understand.
I also came across a utility called pcitop, but afaik it is available only in Linux.
