Better test is to open up a game and start playing. If it's choppy, then it's too slow.
Those fake test "scores" and just selling points.
edit: another thing to take into consideration, yours is just a plain 6600. They are well over 7000 now. PLUS it's the laptopy "GO" version which is going to be a cut down low power version of the 6600 also.
Don't compare laptop parts to desktop parts, the laptop will always loose on speed.
