Minimum System Requirements

So how do you exactly figure out the minimum requirements of the game you made?

Professionally, you test the game on your target platforms throughout development to ensure it runs on them. You also create "budgets" for memory and CPU time up front as a guide to keep your work within the limits of each platform.

As an indie, get as many people to test it as you can, and find a way to measure how well it performs and what hardware they have. Use this data to try and find the minimum hardware required to hit your target frame rate... I guess...
For stuff like system and GPU memory, you should be able to work out how much is required by yourself - you can measure both of these on your own system and it probably won't change ... much ... on other systems. (There are usually slightly higher mem requirements on Vista/win7 due to driver differences, so do your tests on one of those if you can). Also you hopefully know what shader versions you're using in your game, so that will be another min requirement you already know.

For the other stuff (CPU and GPU performance) you'll probably have to do what Hodgman suggests, get some friends to help you test on various systems and see what works and what doesn't.
