Asus has a tradition of producing quality, feature-rich motherboards. The P5E-VM HDMI was one of their best — an Intel LGA775 mATX board based on the G35 chipset. With so many features it made an excellent ATX replacement and stood alone in its class for almost a year. Now, poised to replace it is the Asus P5Q-EM. Sporting a similar feature-set, but based around the new G45 chipset, it has some big shoes to fill.

Our first experience with Intel's G45 chipset was very positive. The DG45FC, Intel's mini-ITX adaptation of the chipset, proved to be very capable and extremely power efficient. Its form factor, however, is very restrictive; it does not even support all of Intel's current processors — you cannot use a quad core with it or anything with a TDP over 65W. For those wanting a little more versatility, the microATX form factor is ideal. The question is: does G45 translate as well to mATX?


Asus' Intel motherboards typically ship with a glossy blue box.
