Hi again will it say if you had an Amiga 2000 And Amiga 3000, both with the same cpu and the same ram the 3000 will be faster?
It's not automatically faster at everything, no. (I'm talking an A2000 and A3000, both with '060 and PIV.) But when the Zorro bus becomes a factor, there will be a noticeable difference. The best way to describe it is that in those cases, the Z3 machine will appear less slow. I ran Quake, RTG scenedemos, IBrowse, and played with the PIV PIP, there was essentially no difference. A video that's slow on the 2000 might be slightly less of a slideshow on the 3000, if it's truly the Zorro bus and not the CPU that's choking. With the Picasso IV, you *will* notice the Z2 limitations with screenmodes above 1024x768x16. After that is where the benchmarks start showing the difference as well.
There are other factors to consider, too. Like I'd rather have the 2000 with a TekMagic, PIV, and awesome NCR SCSI, than a 3000 with the faster bus, but stuck with a Cyberstorm MK2 and motherboard SCSI.
If a guy had both computers, and was only going to upgrade one, absolutely it would make more sense to use the 3000. No doubt. Just don't be too scared off by the Z2 bus in the 2000. Since the OP already has an Indivision in his A2K, it might make more sense to add a Picasso II/Spectrum and an '030 , use it for OCS gaming... and spend a little more money upgrading the 3000 instead.
