Pros: Everything is where you think it should be, and the PCI-E and RAM are well-sited and don't conflict even with larger GPUs. EFI is quite nice and easy to use. Corsair h100i fit easily.

Cons: Side A BIOS was corrupted on mine - I had to switch to the backup and reflash before it would work properly. Remember to try this before RMAing. Initial EFI update hit a hiccup - had to try a second time with instant flash before it worked. Sometimes has a minor USB stutter - probably a driver issue with my install.

Overall Review: Important: as with all motherboards, the blanking plate must go in first, unless you really really really really want to have to take everything apart again. There's also an extra screwhole beyond what's on ATX - it's not strictly needed, so if you're looking at 10 holes after installing 9 screws and standoffs, that's why.

Pros: - Exceptionally fast; while it worked, performance was very good.

Cons: - Stopped working after 30 minutes of use. Oddly while browsing the internet, after having finished any taxing work.

Overall Review: For the very limited time that I had the GPU and it worked correctly, the GPU was fantastic. It was able to play several games at 4k 60fps without dropping frames, and was generally what you would expect from a RTX 3090. However, about 30 minutes into its operational life, it suddenly stopped producing any video output whatsoever. Not even motherboard-produced output (such as the boot splash screens or the EFI configuration) would show; just blank screens. This persists past reboots, reseating the GPU, etc, and the slot/motherboard still works nominally. Now I get to figure out how to return it for repair or replacement. I'll update the review as I follow up with Gigabyte and Newegg.
