Motherboard query

[noobftw]

I currently have an MSI Gaming Plus x470 and it does not allow me to add the Raid Controller Card i need, i  now require a motherboard that will accommodate the below when used with a Ryzen 2700.

1. RAID Controller Card (PCIe 2.0 x8)

2. A single M.2 NVME (?)

3. Mellanox ConnectX-2 10Gbe NIC (PCIe x8 connection)

4. Graphics card (Will work in either PCIe x16 or x8)

 

More importantly, will the Ryzen 2700 allow everything to run at full speed

Someone may correct me but I'm pretty sure there isn't a board that could run all of that with a 2700.

2700 only has 20 lanes, 8 (RAID) + 4 (M.2) + 8 (Mellanox) + 8 (GPU) = 28.

If you ran a Sata M.2 instead of NVMe PCIe M.2 that would save you 4 lanes, and then ran the Mellanox at 4x, you could run the raid controller and graphics card at 8x.

Looks like this board could handle that, but you'd be running the Mellanox at half the bandwidth and couldn't benefit from faster M.2 speeds:

I might have to sell up and go thread ripper then. I should have planned better
