$800 7900 XTX or 5080

I am currently in the process of building a whole new rig. I have all my parts and even the 7900xtx but can’t decide if I should keep the $800 xtx or miss out on the features of the 5080 to save 2-400 dollars. I’ll be pairing with a 9800x3d and honestly can wait a couple of months until stock becomes normal. I just am trying to see what your opinions on missing out on DLSS4 and FG.
