With this latest chipset release, ASUS has created the diverse P5Q series product line, with a total of nine different P45 models announced so far. We say "so far" only because if the company's seventeen P35-based motherboards are any indication, we can expect a few additional models down the line. The fact that ASUS offers such a vast selection of models catered to many different price points is another factor that explains the company's popularity among the D-I-Y computer crowd. The motherboard we are reviewing today is the P5Q PRO, which is squarely aimed towards the mainstream market.
