Tried the nv tweak , got my card up to 571 core , 1000 memory ..Ran the cs-source stress test with no graphical artifacts , funny though , i didnt get a higher score , only time i get a higher score useing that stress test is when i oc my cpu . i guess ill try 3dmark 03 and see if theres any improvment there.
