Question Looking to replace current Motherboard

Below are my benchmark results from userbenchmark.com

I'm looking to replace my current motherboard as it only has 26 available lanes total and I would like to add another video card to my setup and maybe a few other things.. 2 more sticks of ram .. maybe a sound card.. m2 drive.. etc..

I was wondering if anyone could provide me with a few options of motherboards that would be better suited for my current setup. I would like a mobo with bluetooth / wifi built in (but not a deal-breaker).. Something with at least 2 slots for graphics cards.. 1 or 2 slots for m2 drives.. high sata ports.. etc..

Any help is appreciated. I've been building this pc for about 2.5 years now.. maybe a bit longer.. and would like to kick it up a notch..

This pc is primarily used for web / graphic design video editing but of course it gets its use for gaming..

Kind of games played on pc:
Dirt Rally 2.0
Forza 4
Battlefield 5
GTA5
OverWatch
Dying Light
Metro Exodus
SC2

I don't see how your current motherboard wouldn't be sufficient. You have:
  • Two x16 slots for GPUs (that would run at x8/x8)
  • Two PCIe x1 slots (that can be used for sound card/network card)
  • 4 RAM slots (the most you can without getting an HEDT mobo/CPU with quad channel memory)
  • 3 M.2 slots
Regarding getting a 2nd GPU, the consensus seems to be that SLI is dying and getting dual GPUs isn't worth it anymore.

Thanks for the replies guys.

I thought I read something in the article I posted that if I added too many components the motherboard would create a significant bottle neck due to the limited HSIO lanes? Sorry if I seem like a noob.. I don't fully understand how everything works. I was curious about dual cards cause it seemed like the more video ram you have dedicated, the better resolution you can play at comfortably.

So at the moment.. I should be able to have my graphics card connected in x16, an m2 drive + both ssd's, a better sound card and / or a better network card and 4 ram sticks?

First off, RAM is completely separate from PCIe, so no need to worry there. Your GPU will be connected via PCIe lanes that go directly to your CPU, so no need to worry about it losing bandwidth to other devices.

The rest of your PCIe slots, along with M.2 slots, SATA ports, NIC, etc. all connect to the CPU through the chipset. The chipset has a maximum bandwidth of 4GB/s (in each direction, equivalent to PCIe 3.0 x4) to the CPU. So that's where you can start being bottlenecked. But that only becomes an issue if you have heavy I/O to multiple devices at the same time, such that the combined data speeds get close to 4GB/s. Whether or not that could happen would depend on what exactly you do with your PC and what devices you have installed, but I really doubt it'd be an issue for the vast majority of people

As said above, if you want to eliminate the CPU-chipset bottleneck altogether you'd have to get a high end desktop platform like Intel's X299 or AMD's X399. Those chips have more PCIe lanes direct from the CPU, so you can connect more devices before you have to start using the chipset lanes.
