[SOLVED] Will my MSI MPG X570 Gaming Plus Motherboard Support Two Graphics Cards?

[Schunkster]

I am just curious if my motherboard will support two 2070 Super ASUS ROG graphics cards using an SLI bridge? I also have an ASUS PCE-AC55BT installed so I'm unsure how to proceed concerning spacing and compatability. If more information is needed let me know. Thanks in advance!

Multi-GPU
Supports 2-Way AMD® CrossFire™ Technology


Nvidia SLI is not supported.
I would also advise against doing multi-gpu if your RTX gpu is not a blower type.

Thanks for the information! That's what I was fearing, so if I was hell bent on upgrading to two CPUs would you recommend replacing the motherboard? I've never done that before so I'm not how difficult it is.

Which 2 cpus?
What's the purpose of the PC?

I would just be looking to add another 2070 Super ASUS ROG and the purpose is gaming really. I'm looking to run ultra graphics at around 144-165 fps to match my monitors at 2.5K resolution

If only it was that easy. Unfortunately that's not how this works.

That's just not going to work well.

NVIDIA RTX Graphics Card Cooling Issues

With the RTX series of GPUs, NVIDIA has moved to using dual fans as the standard cooling layout on their GeForce and Titan video cards. This is a big change from past generations and has even bigger implications for using NVIDIA graphics cards in multi-GPU workstations. Let's look at what...

I see, what would be your recommendation then as far as dual GPUs go? Or should stick with a good single GPU?

Single strong gpu over multi-gpu every time, unless doing deep learning or some other professional application, which benefit from Firepro or Quadro, and those are using blower designs anyway.
For gaming, multi-gpu has too many downsides:
1)Higher power consumption, obviously, but that also means having to spend more for a bigger and more robust psu.
I don't know your exact cpu, so I'll just use Nvidia's 650w recommendation for this example - a 650w psu with a system running a single 2070 Super, now you're looking at a 850w+ unit for 2 of them.

2)Cooler design: the standard fan models do not handle multi-gpu - or better yet - small spaces very well, with the top card choking against the bottom one most of the time; the bottom one can choke too if it's close enough to another surface.
Blower cards are best in tight spaces.

3)Driver optimization blows.
Some games are fully supported, thus you get the full muscle out of the setup, some don't support it at all, and others are running some half-assed driver crap that hardly does anything compared to single gpu.

4)Micro stutters, frame skips, driver crashes - AKA, the bugs.
