Personally, I didn’t really appreciate Gigabyte’s high-quality products.
In my opinion, their “windforce” video cards also suffered from above average noisy coil audio problems.

But aside from that, it really does seem like you have a lot to do with this company in terms of support/service.
For example, a friend returned a Gigabyte RTX3080 because it turned out to be faulty.
The video card was full factory settings without an overclock burn somewhere on the PCB.
Gigabyte dismissed the claim as “physical damage” and wouldn’t fix the issue, how sad you must be.

It’s a great brand if you don’t need expensive things like motherboards for older computers, but otherwise I’d prefer to ignore it.
It is probably not for nothing that the Z790 Aorus Xtreme motherboard (version: Gigabyte Z790 AORUS XTREME) for the Z790 chipset will not be released in Europe as previously mentioned in Tweakers.
It seems that people don’t trust Gigabyte enough for high-end components and this reflects that these products will eventually die out.
And that they don’t have that confidence can be a good thing because they’ve had previous (service) problems in the past.

But what if you want it all on one board: USB4, 10GbE, PCIe 5.0 M.2, excellent VRM and also all sorts of overclocking features? Then you end up with the pricey ASUS ROG Maximus Z790 Extreme, which also stands head and shoulders above the rest of the testing field when it comes to finish. ASUS has been the parent company in the upper echelon for several generations now — Gigabyte even decided not to release the Z790 Aorus Xtreme in Europe for all this time — so they’re also taking the Ultimate award this time around. You’ll have to dig around really well, because the ASUS model has also only been in drops and scrapes lately. Alternatively, you can still switch to the Z690 version, which of course has the same socket and is pretty much identical.

Gigabyte is also that brand of explosive power supplies recently examined by Gamersnexus, and it also doesn’t inspire much confidence to perfect this technology and then claim that the tests were done incorrectly.

And Gigabyte is also the company that previously modified motherboards with fewer components, which would cause power supply problems without adjusting the revisions, although they no longer do so after the uproar.

Have a couple of old machines with Gigabyte motherboards in use, each for the E4600 and Q9550.
However, the E4600’s Gigabyte board has a strange feature that sometimes limits one hard drive to 3.8MB/s.
You can’t get rid of that with a power outage and the system becomes very slow as a result.

It now has old Seagate Brakkecuda drivers in it, which I never thought of in terms of reliability (they have some minor smart bugs but they are old so excuse me) but it seems like this issue is really down to the motherboard.
A workaround to get around this can only be done by physically swapping the SATA cables to the ports on the motherboard and then swapping the order in the bios (if I remember correctly) to boot from. Simply changing the SATA cable between the disks meant that the second hard disk was limited to 3.8MB/s.

I haven’t had any problems with the board in my Q9550 PC yet, its a GA-G41M-Combo (2.0 revision) which was one of the last to get new in 2015 when my Asus P5KPL/1600 motherboard broke (most likely that due to the unbranded 580W power supply which has also now been removed). I don’t know what exactly is in the E4600 computer.

By the way, I used to have a gigabyte 8500GT, like a passive video card.
It’s not designed for higher workloads because with games, we’d happily heat it up to 100 degrees Celsius and higher.
It barely lasted a year until death, with nice accidents leading up to it.
