I'm just writing this to tell my 3dMark06 score for comparing as I have a similar system but with a faster version of the CPU (also my graphics card is factory OC'd which makes it slightly faster). Since the OP asked that if he had a 6000+ CPU he would get scored of 11k+ I can just agree to some other posters in the thread that he will not. Last evening I overclocked my CPU some (the 5600+ isn't that overclock friendly sadly so I only raised the frequenzy with just over 100 MHz) and got a score of 8714. Before the OC it was just above 8500. Since it seems that it is quite safe to overclock even the graphics card some I'll do that tonight. People seems to have them at 600 / 1800 with load temperatures at around 80C with base fan which is far from too hot. Anyway, with the gfx card overclocked I probably see scores of 9000+ but that's it. So to the OP, the only way for you to see far higher 3dMark06 scores would be by upgrading to a Core 2 Duo and then overclock that one. At least without also upgrading the gfx card to a GTX.
