dude ur way below what you should be getting.
with my phenom 955 @ 3.8ghz, 2gb of ram, hd 3870 overclocked i get little over 13,000 points.
You don't know what you're talking about. You're comparing your overclocked system with his stock system. Try running at stock and you'll get much lower. 3dmark06 is very cpu dependent. My q9550 with 2x 4870 get 16500 at stock, but 24500 with the cpu at 4.3ghz.
@OP Your score sounds right for stock. Try overclocking and you'll get higher numbers.
