Curious to know about some of your CPU scores as I got 7,108 with my athlon 64 3000+ Venice.
Use Hot CPU Tester Pro 4 LE which you can download here-
Click benchmark on the left and then "Run Benchmark"
I am VERY curious to see what you dual cores get! Also, I would reboot before doing this...I originally got a 6,500 but that was after 2 hours of battlefield 2.
