system requirements tool

hello!
I want to make a little tool that reads out the system information like Cores, cpu clock, RAM and GFX information and then compares them to 3 sets of requirements (like low, med and high)

Can someone help me in that or show me something similar to it?

Piece of cake! On my machine, I just use the shell command readOutTheSystemInformationLikeCoresCPUClockRAMAndGFXInformationAndThenCompareThemTo3SetsOfRequirements low med high
