Because of inadequate VRM cooling on the HD 4870s and the fact FurMark heats up those VRMs a lot FurMark can overheat and even kill most HD 4870 cards. That is the reason behind the drop in FurMark that has been noticed by a lot of people. Basically, instead of fixing the problem with VRM cooling ATI appears to have just nerfed FurMark so that it cannot cause the cards to overheat during the stress test. Some people have suggested that renaming the FurMark executable to something else (e.g., fur.exe) allows to bypass the driver nerf and have FurMark behave the same as it would have in 8.7 or before. GPU-Z 0.2.7 is good for monitoring VRM temps while running FurMark in windowed mode. Seems that FurMark has become a real thorn in the side of ATI.
