I had two of these cards and neither had RGB. I think your issue is different though. There seems to be confusion over these gigabyte cards but one has RGB and one doesn't. The Windforce OC 3X has no rgb.
Yeah, I ran into a similar thing. No RGB on mine. Basically from what I can gather the GAMING OC 3X has RGB, but the WINDFORCE OC 3X does not have RGB. As far as I can gather the RGB is the only difference between the two. $50 for a logo is a lot so I'm not too bummed.
Yeah, I don't love them but until I get some right angle cables that feels like the best way to position them.
