While NVIDIA's GeForce RTX 3070 GPU works just fine with PCIe 3.0 slots, it's best to grab a motherboard with a PCIe 4.0 slot to make the most of its graphical prowess. We've rounded up the best motherboards with PCIe 4.0 slots for both AMD and Intel processors.

Best AMD motherboards for NVIDIA GeForce RTX 3070

ASRock B550M Steel Legend (opens in new tab)

Budget B550

The B550 is a little less advanced than the X570 chipset, but you still get PCI 4.0 support. The ASRock B550M Steel Legend also comes with a 10-phase power delivery design, which is pretty good for the price, as well as support for super-fast RAM and an M.2 slot for installing your favorite OS.

ASUS Prime X570-P (opens in new tab)

Entry X570

You don't have to spend so much on an X570 motherboard. ASUS also has the Prime X570-P, which is considerably more affordable than our top pick but still comes with PCIe 4.0 support, metal heatsinks for the VRMs, high-quality components, and more highlights for a stable, powerful AMD PC.

Best Intel motherboards for NVIDIA GeForce RTX 3070

Intel doesn't officially support PCIe 4.0 yet but will offer the said functionality to match AMD with the launch of Rocket Lake processors. That hasn't stopped motherboard makers from preemptively adding PCIe 4.0 support into certain motherboards right now. So, while you can technically buy PCIe 4.0-ready motherboards for Intel CPUs, you'll be stuck on PCIe 3.0 until the new CPUs launch.

We'd recommend against buying an Intel motherboard right now for PCIe 4.0 support. Not until Intel launches its new Rocket Lake processors. If you absolutely must buy a new motherboard today for a 10th Gen Intel CPU, we've rounded up a few of our current favorites.

Choosing the best motherboard for NVIDIA's GeForce RTX 3070

If you want to build an entirely new system right now and must have PCIe 4.0, we'd recommend AMD since its Ryzen 3000 series processors already support the feature on X570 and B550 chipset motherboards. The ASUS ROG Strix X570-E (opens in new tab) is overall a brilliant motherboard with everything you need for a capable PC.
