What I discovered is that the G-Rex systems had considerably faster bus speed results, averaging 20M/s. One system (A4k 060@66 IIRC) managed close to 40M/s in that test...
Grex 1200 and Grex 4000 use the same PCI bridge logic as BVision. The effect is that the Grex bustest results are always the same as for the BVison card.
Grex bustest results depend on the BlizzardPPC/Cyberstorm card version. 40MB/s is a rumor only
