OCCT 3.1.0 shows HD4870/4890 design flaw - they can't handle the new GPU test !

Perhaps more of Nvidia's processing power are "reserved" for PhysX calculations. I wouldnt be surprised if many of those transistors are wasted anyways on 32 ROPs, 512-bit memory interface, and espeically PhysX.

After all, nothing ever pushes closer than 99% of the theoretical maximum. Some of the older cards were so inefficient, like G92 cards, in only getting within 75-85% of the theoretical maximum for fillrate tests.
