Our take on the MSI Desktop Motherboard AMD Socket AM3+ ATX 990XA-GD55

The MSI 990XA-GD55 is an ATX motherboard for AMD Socket AM3+ processors, built on the AMD 990X chipset. It carries four DDR3 slots for up to 32GB, two PCIe x16 slots for SLI or CrossFireX, and SATA 6Gb/s plus USB 3.0. It suits builders reviving or assembling a Phenom II or FX-era system who want multi-GPU support and modern ports on a budget. Against newer AM3+ boards it trades away features like more SATA ports and higher memory speeds, but covers the essentials for a gaming or general-purpose build.

Questions and answers

Which CPUs does the 990XA-GD55 support?
It uses the AMD Socket AM3+, so it takes AM3+ processors such as the FX series and also accepts many AM3 Phenom II chips. Check the board's CPU support list for the specific model before buying.
Can I run two graphics cards?
Yes. It has two PCIe x16 slots and supports both NVIDIA SLI and AMD CrossFireX. The slots split bandwidth when both are populated, so plan for that in a multi-GPU build.
How much RAM can it take?
Four DDR3 DIMM slots hold up to 32GB total. DDR3 is the only memory type it accepts, so DDR4 or DDR5 modules will not fit.
Does it have USB 3.0 and SATA 6Gb/s?
Yes. The board provides USB 3.0 ports and SATA 6Gb/s headers for fast drives. Count the ports you need, since the total is lower than on newer chipsets.
Is this a good board for a new build today?
Only if you already own an AM3+ processor and DDR3 memory. The platform is old and capped at DDR3, so a modern socket gives you far more performance and upgrade room.
Where is the MSI Desktop Motherboard AMD Socket AM3+ ATX 990XA-GD55 cheapest?
At CPU Republic LLC, for $552.70, as of our latest check.
