GA-990FXA-UD3 Motherboard
great motherboard for AMD, 3rd one down from the top and will run the FX-9590 CPU, works the beast and easiest than any motherboard i have had, only one thing it is a 3 year or so old board and already the CD that comes with it don't work very well with windows 10 and a lot of the programs for some of the specialties on the motherboard don't work, some of the this you can find your self or they just aren't needed anyway, just call it a motherboard that works good, a used one without the CD you only get the 4 software apps for windows 10 at the gigabyte website or find a CD for it, i happened to get a new one with everything so luckily i got the CDVerified purchase: YesCondition: Pre-owned

990XA-UD3 r5 in good condition,works accordind to specs
First of all, the product I was buying was not anymore available. I accepted to replace it by a similar product 990XA-UD3 R5, with less capabilities.It works well as is. The slowness is bound to the storage media ( hdd at present time) try to improve with ssd. On the previous FXA it was possible to use NVMe with a bios modified, it worked just fine... It seems, it is not possible to do on this old board. It the game!Verified purchase: YesCondition: Pre-owned

Great mobo!
This is a great mobo for a good price. I only had 1 issue, I run linux and the USB ports didnt want to work right in the OS until I enabled IOMMU in the bios. Overall this was a great board for a great price. This did not come with the I/O plate for the ports/back of the computer but I was able to find one for cheap. If I would have bought this brand new I would have spent over twice as much.Verified purchase: YesCondition: Pre-owned

Gigabyte 990 Series
This is my flagship motherboard. It is # 1 of all motherboards in my book. I install a AMD FX-4350. Talk about fast. The cpu is running at 4.2 GHZ.. I use a Patriot SSD Hard Drive. I use HyperX Fury 1866mhz memory. Evga graphics card and a evga power supply. I highly recommend this motherboard.Verified purchase: YesCondition: Pre-owned

Good board, but a little finicky with Ubuntu Linux
I'm probably a fringe user because I'm using this gaming enthusiast board for an Ubuntu install. I had some major issues with USB and PCI devices losing power until I stumbled onto a suggestion to turn on the IMMOU controller. Now all devices work fine except USB 3.0 ports on the back. I'm not using the front USB, so I can't say whether that has power problems or not. Other than the USB 3.0 back ports, I say this board is working great for my purposes.Verified purchase: YesCondition: Pre-owned

Good to go
Needed to replace an AMD FX board that blew. Didn't need to do complete upgrade, it's a just a general purpose PC. Yes it'll play most games in regular setting, with the GPU I currently have. This board will keep up with current demands with the right CPU, and GPU. If your upgrading or replacing board for AMD FX series CPU, this was good to go.Verified purchase: YesCondition: Pre-owned

Gigabyte GA-990FXA-UD3 Ver.#4 The best Motherboard for the AMD AM3+ cpu!
Great price on a great Motherboard. The ver. #4 is the best because the Memory dim slots are further away from the CPU socket. Making it better for higher heat sinks on the memory sticks. Everything went together just fine. Works Great! Thanks!Verified purchase: YesCondition: Pre-owned

Great Board For Gaming & Multimedia
Very fast due to the chipset and overclock capabilities. Has a 108 DB signal to noise for the audio plus Dolby!!!! Can handle any graphics card and whatever cpu you decide to slam in, It'll still manage to suprise you at just how much power it can squeeze out. Overclocked my FX-4350 from stock 4.2GHz to 4.7GHz with ease. I Couldn't be happier honestly. Recommend this MOBO to anyone and everyone.Verified purchase: YesCondition: Pre-owned

The most versatile AMD motherboard available.
This board will very literally run all AMD processors on the AM3+ socket including the 220 watt ones. It will run 2 high power video cards. It will run 32gb of any speed of ram your processor's memory controller will handle. Roomy. The integrated sound chip is fantastic, especially playing GTA5. This was the Revision 4.0 board.Verified purchase: YesCondition: Pre-owned
