I did a lot of research before I bought my 4090 and the Gigabyte Gaming OC seemed like the best bang-for-the-buck (there being a LOT of bucks needed for a 4090) other than the FE which wasn't available when I was looking.
I got the Rev 1.1 version (shopped around an C-Orbit delivered) because they (allegedly) have better power stages than the Rev 1.0.
Performance is mind blowing!
I'm not going to be overclocking, so don't need a Strix or similar, so this seemed like just what I needed and hasn't disappointed.
Given the weight, it definitely needs anti-sag support and the bracket supplied with it fitted on my MB mounts (Tuf 790) and just about fits snuggly resting on the USB 3 plug.
All in all a good value card compared to other 4090s (let's be honest, ANY 4090 is a luxury item unless you need it for work, so "value" is relative for a 16-hundred quid GPU).
Finally, it's the first time I've ever dealt with C-Orbit and they were brilliant!
