As someone said, go to the online result browser.
then log in and use search and compare from your console.
Then you can hit either approximate cpu specs or exact and see who has your set up.
Now so many being over clocked and out of spec and bios flashes to report other hardware this isnt always acurate but somewhat.
You can then pretty much narrow it down.
Now also you can go to their forums and in the section 3dmark 06 post this exact post and question and often you will find a lot of people willing to compare with you.
I use it for an idea of what a rebuild would offer me.
I went from 18k in 03 to 42k, when i saw the difference knowing the tests I was able to get a good idea what to expect for my gaming performance based on the scores.
Knowing how my 18k system ran games, and seeing a new builld would be 3x faster in that test I could summize it might be at least twice as fast in games that I already play that are also used for benchmarks.
I cant seem to get over 12k on 06, I did once but the specs were out due to an overclock and the orb wouldnt publish it.
