ASRock 890GX Extreme4 Motherboard Review

Rating: 9.0.

ASRock aren't often considered as one of the top motherboard manufacturers around but at KitGuru, we think their products are somewhat underrated.  We recently looked at their P55 Extreme4 Motherboard which walked away with our most prestigious ‘Must Have' award.

Today we are going to look at the 890GX Extreme4 Motherboard which is their attempt at a high-end AMD motherboard.  We look forward to seeing if it performs as well as its Intel counterpart with our Athlon II X4 635 processor.
