MSI 790GX-G65 ATX Motherboard

The MSI 790GX-G65 Motherboard

AMD's Phenom II has made it fashionable to sport AMD CPUs in the enthusiast market once again. Phenom II is currently split across two nearly identical sockets, AM2+ and AM3. Today we've got MSI's 790GX-G65 motherboard, one of two AM3 motherboards they currently manufacture. The 790GX-G65 motherboard is a mid-range motherboard that shares some of the overclocking features of the more expensive MSI 790GX GD70 while maintaining a much lower price. Today we'll show how a board with a modest price can still be successful at stock and overclocked speeds.








The 790GX + SB750 chipset that the 790GX-G65 is based upon is a familiar face with dozens of boards utilizing this chipset with AM2+ and AM3 sockets. Unlike motherboards of yore, the 790GX chipset has much less work cut out for it as the memory controller is integrated into the CPU. However, unlike past motherboards, the 790GX northbridge features an integrated HD3300 graphical processor with 128MB of DDR3 for superb onboard video performance and smooth high-definition video playback.

A buyer must be very careful with AMD's current lineup of CPUs. Since the 790GX-G65 uses an AM3 socket, only AM3 Phenom II CPUs will physically fit in the socket and function properly. Currently, only the AMD Phenom II X3 720 Black Edition, Phenom II X3 710, and Phenom II X4 810 will function in this motherboard. Don't worry though, there are many upcoming AM3 CPUs and this board will support them all as it can support up to 140w CPUs. Below is a short chart highlighting the major features of the 790GX-G65.
