yes do a fresh install again don't tm anything over. load geekbench and check score. the new score is on a fresh (mp dvd disk) install with only geek bench you will get around 8200 if it is 32 bit geekbench. then click and drag 1 file/folder from the tm at a time. run the 32 bit geekbench if the geekbench drops that is the file/folder . no drop do the next file/folder
actually more like 8800 in a baseline machine. (Mine got 8808 with only FCS installed and not running and Geekbench 32-bit) - Anything below 8000 is bonkers for the latest Quad, as they definitely can get up to 10,000 (Mine will get up there eventually - it defo needs more RAM xD)
