Is this card 13.23" long (336mm) as shown in the picture or is it 300mm (11.81") as shown in the specs?

The card is not 13". It looks like it's about 11 7/8" (hard to measure precisely while it's in the computer), so I'd say 11.81" is probably right.

Does this VGA card come with an anti-sag bracket?

Yes, the GIGABYTE GeForce RTX 4070 Ti SUPER GAMING OC 16G Graphics Card comes with an anti-sag bracket.
