A few weeks ago, the ASRock 890GX Extreme3 motherboard was tested at ocinside.de and the result was excellent with the updated BIOS version. In this review, an equivalent Micro ATX board with 890GX chipset is overclocked to the limit. This mATX motherboard has also integrated USB3.0, SATA3 and eSATA3, as well as the fast onBoard HD4290 GPU with sideport memory. Let us see, if this small 890GM Pro3 mATX motherboard can keep up with the large 890GX Extreme3 ATX board.
