The benchmark doesn't have very stern requirements for running. DirectX 9 and Windows Vista/7 are pretty much all it needs. If you're posting in this thread, your computer most likely is beefy enough to run it. It may not run it WELL, but it will run it. If it runs, you should be able to crank out an Au Ra. It might be slow and jerky if your computer really does suck, but give it a try before assuming that the benchmark won't work for you!
