X670 Vs B650e is the price worth it?

I'm looking at the two particular motherboards:
- Gigabyte Autos Elite X670
- ASUS B650E-E Gaming WiFi

My understanding is that the X670 has more connections (USB ports) but both have PCI 5.0, M2 slots, support AM5 (7800X3D) however the X670 is supposed to be the more powerful of th two which I don't understand.

If I were to plug in two NVMEs into the PCI 5.0 slot then my understanding is it will impact the graphics card performance but this is the same with both boards? Is this a fair comparison and should I be heading towards X670 / X670e boards?
 
Haha I am aware of the recent controversy around their motherboard's particularly with the X3D chip. I've always gone gigabyte but ASUS were / still a top brand despite the current issue?

What are you using the pc for ? For the majority of people Gen 5 isn't of much use. Unless you need Gen 5 SSD's for some reason then a Gen 4 board is more than fine, and saves you money in the process.

X670E has PCI-E 5.0 graphics.
B650E has PCI-E 5.0 graphics.

PCI-E 5.0 M.2 slot is optional for a non-E board, but there's usually one, except for all PCI-E 4.0 boards like the B650 Tomahawk or B650 Gaming X.

So, the X670 Aorus Elite you mentioned has PCI-E 4.0 graphics and the Asus Strix B650E-E has PCI-E 5.0 graphics.

What do you mean by "powerful"? In terms of: do you get more performance for an average build (e.g. 7800X3D, 2x M.2, 1x PCI-E 4.0 graphics card), then no. X670 is not more powerful than B650.

B650E and X670E boards can offer 2x PCI-E 5.0 M.2 with no impact on the graphics card, but any further PCI-E lanes will share them.

An example of this config is the ROG X670E Hero (minus the M.2 expansion card) and for B650E, the B650E Aorus Master (slot A and D).

Many B650E and X670E boards will try to offer more PCI-E lanes than the CPU/chipset has available, which is why they still end up sharing.

Asus B650E-E config:

B650E has 36 lanes available, up to 24 of which can be PCI-E 5.0.

CPU GPU lanes: max 16.
- 16 PCI-E 5.0 go to the primary PCI-E slot.
- 4 PCI-E 5.0 go to the second PCI-E slot (reduces primary slot to 8 when in use).
- 4 PCI-E 5.0 go to M.2 slot 3 (reduces primary slot to 8 when in use).

CPU M.2 lanes: max 8.
- 4 PCI-E 5.0 go to M.2 slot 1.
- 4 PCI-E 4.0 go to M.2 slot 2.

Chipset lanes: max 12.
- 4 PCI-E 4.0 go to M.2 slot 4.
- 4 PCI-E 4.0 go to the third full length PCI-E slot.

Why did Asus not make all 8 CPU M.2 lanes PCI-E 5.0? I don't know, maybe for differentiation with their X670E-E board.

Another vote for no Asus.

I always go for the cheapest board with the features I need. I've only have one X chipset board and it wasn't worth it imo. If it ticks your boxes the buy cheaper.
 
I've had good experiences with Gigabyte in the past but the auros master I'm struggling to justify the cost for it. At £400 I'd rather invest into the graphics card. I'm mainly gaming and video editing so had 7800X3D in mind paired with GSkill DDR5 6000 CL30 (Z5 Neo).

ASUS board seemed reasonably priced but I'm open to suggestions :) ideally max £300
