I replied on the post that I wouldn't even do it, but the reason if that I was and am at work right now. I did the test on my PC this morning and my results:
169%
I figure it could be a good place to gage your system. When you test your system against Alienware top notch, if it is over a certain percentage (300% for eq.), then maybe it is a good indicator that you should start thinking of getting a more recent PC, or upgrade.
