P45's and DDR3 don't seem to produce very good results, so this board should definitely be better than your P5Q3. If you are going to stay around 3.6GHz - 4.0GHz, this board should be fine for you. However if you want to clock higher go grab the UD3P, that clocks quads like nothing else.

Some people got good samples of the M2F, so you might be lucky, others have got average boards and some were just hopeless, warped etc. Radaja went through 5 boards until he got one that was up to standard regarding build quality. Asus really messed up the quality control on the Max 2 Formula.
