I hope this chears you up some, but remember that Microsoft ended support for the two windows operating systems you mention, more than a couple of years ago..
End of support for Windows 98 and Windows Me
July 11, 2006 will bring a close to Extended Support for Windows 98, Windows 98 Second Edition, and Windows Me as part of the Microsoft Lifecycle Policy. Microsoft will retire public and technical support, including security updates, by this date.
Existing support documents and content, however, will continue to be available through the Microsoft Support Product Solution Center Web site. This Web site will continue to host a wealth of previous How-to, Troubleshooting, and Configuration content for anyone who may need self-service.

http://www.microsoft.com/windows/support/endofsupport.mspxMicrosoft is retiring support for these products because they are outdated and can expose customers to security risks. We recommend that customers who are still running Windows 98 or Windows Me upgrade to a newer, more secure Microsoft operating system, such as Windows XP, as soon as possible.
Customers who upgrade to Windows XP report improved security, richer functionality, and increased productivity.
The Amiga was always beyond it's years, but I "imagine" if you ran the 3d software on a recent PC you might be writing a different kind of post. Why do we have to always compare apples to oranges here and ancient hardware to ancient hardware of different eras..
I would much rather hear or see the stuff you are coming upwith creatively in Imagine..
