AMD 790FX 4-Way Motherboard Roundup

AMD 790FX 4-Way Motherboard Roundup


AMD 790FX Roundup

In November last year, AMD officially launched their Spider platform, consisting of the AMD Phenom processor, 790FX core logic chipset and the ATI Radeon HD 3800 series graphics cards. In our launch article , we focused on the technology that was put into the 790FX chipset, and the introduction of the Phenom's new AM2+ socket type. However, you'd probably have noticed that things have still been relatively quiet on the AMD front, even after the high-profile Spider launch worldwide.

We've actually had samples of AMD 790FX motherboards sitting in our labs since then, but a proper review has been long coming due to circumstantial delays in getting all the necessary components to run, such as a working Phenom processor. As more motherboards arrived, and still no processor in sight, it was obvious that we now had enough boards for a comparative roundup instead, effectively killing four birds with one stone. So, when AMD graciously sent us an AMD Phenom 9900 processor, gears were set in motion for some intensive testing of four major AMD 790FX enthusiast motherboards. Our contenders: the ASUS M3A32-MVP Deluxe, DFI LANParty DK 790FX-M2RS, Gigabyte GA-MA790FX-DQ6 and MSI K9A2 Platinum.
