i'm sorry bro, but alibabar is right.
since your screenshot is in 1024x768 i'm pretty sure the bench was run in that resolution as well. that would expalin the way too fast gt1 (+20% to other top 3 guys) with much lower clocks. default in 3dmark06 is 1280x1024. if your monitor is too small and doesn't support it you have to use a bigger one.
also, do note that it's vital that the resolution is always visible. i saw a few other 3dmark runs from you where the resolution is also not visible....
