I need to upgrade my video card. I'm considering a 7900xt or 4070Ti. The problem is my case setup prevents me from using a support beam. I'm not concerned of about sag in terms of cosmetics. I'm a little concerned about damage or anything that would interfere with the functionality of the video card. What should I look for when searching for card without sag? The smallest cards are 2.5 slots. Does the 7900xt sag? Is there a weight threshold that I should look for? Thank you.
