I use em for the same reason tkop does. Bench the system. Overclock something. Bench it again.
Also a good way to tell which drivers are the best.
Speaking of which, those Omega drivers that everybody likes are terrible. They made my score in GL Excess drop by 20%. Faster than ATI drivers my a**. Another thing I just found out. With Omega drivers, setting the TV as an extension of my desktop causes the computer to crash.

But like Vass asked, are you using a 32-bit or 64-bit version of Windows? My computer's hardware isn't even the same league as yours and it scored around 4500.
