Best SLI Motherboard am3+ 990fx chipset

[Hokosaki]

I am going to be running 2 GTX 980 6gb graphics cards in SLI and an AMD FX8350 FX 8 core processor so I'll need a board with socket AM3+ and the 990FX chipset and supports SLI. I would also like to configure it for running triple monitors. I did some research and found that the Asus Sabertooth mb is AM3+ and has the 990FX chipset and supports SLI. Does the motherboard control the use of multiple monitors or is that the graphics software?

Gigabyte UD5 and UD7 MBs with 990 chipset.

Now wait, just before you jump into this I need to warn you about something.

I am currently running 2x GTX 760s with an FX8350 and an Asus CROSSHAIR-V FORMULA-Z and I have many [first world] complaints.

1. The FX8350 while shown as having 8 cores only has 4, but has 8 threads. So its really about the performance of an i5

2. SLI is really overrated... In my two years of owning this PC I have never seen a software or game support SLI accept for the Adobe Suite supporting the total CUDA cores, but thats another story.

3. Restating my previous point, SLI is never used in games so its a MEGA waste in money. Unless you already have the components ofc.

4. Always buy a single graphics card that is the price equivalent of the two cards you plan to SLI. In other words buy the fastest card on the market you can afford at the moment.

5. If you just get one 980 you can save up the extra money for a newer generation GPU when they are released next year.

These are my two cents from having a similar system for two years. I am really critical so these points might not bother you. As for your two monitors, you can always get a secondary cheap card just to run displays, but a newer NVIDIA graphics card can easily run 3 monitors.

Hope this helps!

Thanks a lot for those replies. That gives me more options to ponder.

That is 100% not true their tons of games that support SLI. Your not going to get 100% scaling but they do support it.
Just a quick google search shows this. I have ran SLI and Xfire.

It's not worth buying a new motherboard for a 4 year old FX processor to run SLI.
The video card will be what runs the 3 monitors the motherboard has nothing to do with it.

Thanks for pointing that out, it's been 8 years since I built a computer so I'm not up on new hardware and the searches I made did not bring up the newest stuff. I just found some new info and I think I'll go with the GTX 1070. I know it runs hot but I'm installing liquid cooling for the whole system. As for a MB I think I'll go with the Asus M5A99 FX Pro R2.0, it had good reviews and it's right for my color scheme.

1. Depends on the task and which i5 for instance a 6600k will beat the 8350 in everything except for file compression. In tasks like gaming there are i3s that perform better than the FX 9590 in many games.

2. I have run many SLI rigs over the years and have seen more games support it than not.

What a way to take my statement out of context. I see what you mean about not 100% scaling and while that can be true in some titles many titles outright just don't work correctly while using SLI.

In some newer games like BF1 and Overwatch I have had to disable 1 of my GPUs to run them without micro-stuttering or strangely scaled performance.

Check out this post, while it does not express my full opinion on NVIDIA it sure does show my opinion on SLI. This post was a year ago and still they could see what was happening to SLI. http://www.gamefaqs.com/boards/916373-pc/72920665

Sorry if you misunderstood my statement as misinformation, but I was simply giving this guy all the facts he needed. About SLI, I was kinda wrong and was trying to prove my point a little hard, but that doesn't change the fact the SLI is dying and support is being lost from developers.
