Realtek L8200A LAN may be a dealbreaker for some people as it's proprietary to ASUS which is a pain for any non-Windows OS as well as for longterm driver support. If you want an Intel LAN that will be well supported in the future, then the lowest board in ASUS' stack is the Prime X570 Pro for $250...
i know this post is old, but according to the linux guys, its just a rebranded realtek RTL8111/8168/8411 and works just fine.

I'll put my name down on that list too! but my 2600X is still good enough for the games I like to play atm.

boombeef Bang for the buck, at the limit of "budget" I'd guess going with GIGABYTE X570 AORUS ELITE that is at Newegg now for $200. I am one for not changing mobo/cpu/ram for years at a time so will probably keep this one for 5+ years. Intel Lan + Power delivery peace of mind sells me.

I do have a question for anyone using dual NVMe on that mobo or similar Gigabyte layout. Heatsink for the bottom drive ever have issues with GPU? Any advice thread or someone has measurements of space available? Maybe another thread that has this? I am looking through the Aorus owners thread slowly.

If you're buying a Ryzen 9 3900X or 3950X then both are bad choices. There's mosfets on the back of the Gigabyte X570 Gaming X that don't receive any cooling in a normal case scenario , despite it being 10 high side fets and 20 low side fets (it's a double low side fet design). Couple that with the lack of USB 3.1 gen 2 and worse audio (ALC887 instead of ALC892) and I don't see why you would buy it.


Mathematically if you have a 105W CPU with 140A current limit:
140A/8 = 17.5A each set of mosfets and at V_GS=10V the RDS(on) of each low side fet is 2.8mΩ
140A/10 = 14A each set of mosfets ; each low side fet has RDS(on) 4mΩ which means with a doubled low side it's 2mΩ


If you want a Gigabyte board buy a X570 Aorus Elite, it's far better than B450 and X570 Gaming X and has Intel LAN + 12 powerstages instead of discrete mosfets (6 phase PWM doubled to 12). It's the difference between 90°C VRM (near the limits of what is ideal) when overclocked R9 3900X or 60°C VRM (cool enough to last years).

Nice explanation, Alpha.... Thanx...

I WOULD LOOOOOVE to buy an Aorus X570 motherboard, but my budget ins't that robust as I wanted to... I need to buy PSU, mobo, CPU, GPU and RAM, on a $600 budget...

Anyways, I made my mind and I'm gonna go for the Ryzen 5 2600X/Aorus B450 Elite combo... It's the best choice, so far....

Cheers!!...

Thanx for the response, Alpha...

Correct me if I'm wrong, but hasn't the Tomahawk a weak VRM system?... I mean, according to the web page and pictures, it only has 4+2 VRMs, while the Aorus has (again, according to the webpage) a 10+2 VRM system... I mean, it seems a lot better...
I know you're responding on the "Bios update" matter, but I've been rambling my mind this past days about that downside of the Tomahawk...
I have always chosen my motherboards as robust as I can get, specially because I like OCing...

On the audio side, I don't really care that much... I have a Creative Soundblaster Recon3D Fatal1ty...

Anyway, again thanx for the answer, but I don't see getting a Ryzen 5 3600 and a B450 mobo, AND be able to update the Bios to make it work... I asked Aorus official and Gigabyte official, and still waiting for an answer....

If not, I'm getting a Ryzen 5 2600X and the Aorus B450 Elite... I think is a really good motherboard for the price... Those X570 motherboards available at this moment are more expensive as I can afford...

Cheers!!!....

LexLuthor I'm on the same boat, but a little worst, I think.

First of all, I made a thread already about updating my PC, but for another reason....

Second, I'm planning on buying a Ryzen 5 3600, but I can't decide which mobo I should buy. So far I had made my mind going with a Gigabyte B450 Aorus Elite, but after reading some forums, I came with one mayor problem: I don't have any other CPU spare to update the Bios....

So now I'm in a crossroad: either buy a Ryzen 5/7 2000, or find a B450 motherboard that allows me to update the Bios without a CPU. So far, I got stuck with the Gigabyte X570 Gaming X, which is one of the most cheaper in hand.

Which one of the B450 motherboards allows you to update the Bios without a CPU?...

Thanx in advance...

miklkit I paid $170-180 for my Sabertooth gen2 boards new from Newegg. Others were buying CHVs for around $220. Again I was looking at Newegg for prices this morning. Up to $700!



Gen 3 Sabertooth? $190? I really don't remember that one.

Three years ago the most expensive AMD board was $220 and now that model is $400. Inflation my a$$! Due to the price gouging I will be buying some "meh whatever" low end board and pass on OCing.

ASUS Crosshair VI Extreme (AMD X370) $349.99
ASUS ROG Crosshair VI Hero (AMD X370) $254.99
ASUS Crosshair V Formula $237.99
ASUS SABERTOOTH 990FX R3.0 $219 (reviews Rev 1.01 and Rev 2. where $199)
SABERTOOTH 990FX/GEN3 R2.0 ???? added PCIe Gen3 via expensive PLX implementation ($280 or $300 don't recall)

miklkit, I do remember you from the SABERTOOTH owner thread, do you recall if it was $80 or $100 more than the normal SABERTOOTH 990FX for the limited edition PCIe Gen 3.0 board.
