I could imagine this thread ending up pretty much here.
A PC can do smooth scrolling. Windows can do smooth scrolling. Multi core CPUs doesn't make a PC more similar to the Amiga, that's just silly. The custom chipset used in the Amiga cannot be compared to multiple CPUs or even a single CPU. Post '95 PCs use dedicated chipsets, bus mastering, DMA etc. just like the Amiga did. These concepts are not specific to the Amiga, but rather hardware solutions which have been used in many different designs.
Wolf3D ran fairly well on my 286, even though this CPU is rather inferior compared to the 68k (imho). The biggest reason is chunky graphics, which both the Amiga and ST lacks. Planar graphics may have been a good idea in '84, but it was a bloody bad decision for the Amiga 1200 and Atari Falcon.
