The ORB is the Online Results Database. When you run 3DMark, you can upload the results. You will have to make a (free) account online. You will see your score online, and there will be a check box next to it that states 'publish'. Check this, and hit 'Update' on the bottom. Then, a link will appear under your score. I want that link
5000 3DMark06 is a lot better...but not stellar. I got higher than that with a single X1900XT and an Opteron 170 at stock speeds!
However, your CPU is single core, which is no good for 3DMark06. It loves dual core CPUs. A Pentium D 925 ($139) or even a 945 ($167) would give a nice boost! Or save up about $500 if you can and go for the newest tech you can find for that money (Core 2 Duo, or whatever AMD has by that time). Prices in the US.
