Just run it and give it about 20 minutes, check your score and post it here with your system specs and you're done! The bench consists of 3 different parts: DX9, DX10 and DX11 so if you have at least a DX9 capable card and and Windows Vista or newer, you will be able to run at least some of the tests.
My scores:

i5 2500K @ 4GHz, Geforce GTX 560 Ti, 8GB DDR3 1333MHz
