You want to do amateur or power-level computing? Then there is no other choice than Windows! Period.
As a Windows user you don't have to spend tons of a money for a Mac PC (sorry Mac guys but Mac is nothing else than an expensive PC now) and you don't have to waste time on forums to learn how install stuff.
All that Linux/Mac can offer you can get on Windows and get is better.
I spent many years working with Linux but it was always only my second choice.
Sorry Linux friends, but I said it.

Memory limitations for Delphi 7
Application developed under Delphi 7 are 32 bit, and they can only access a limited amount of RAM.
This Microsoft document says that the limit is 2GB.
So I have made some tests and indeed I could not allocate more than 2GB of RAM. However, The document also says that 32bit applications could access up to 3GB of RAM if the following conditions are met:
The OS uses the /3GB switch
The application has the IMAGE_FILE_LARGE_ADDRESS_AWARE flag set.
Here is the official documentation for /3GB switch.
There is a possible draw back when using the /3GB flag: the OS is squeezed in to 1GB of RAM, instead of 2GB. In some situations this might not be enough. However, I thin this is unlikely. 1GB should be enough for OS.
