Question Should i waste money on Crossfire...

Hi, tomorrow im receiving my CoolerMaster HAF X case (finally), starting a brand new project build.
The specs that are going into that case are listed in my signature, and it will be my main rig, used for playing LoL, FPS games and some single player AAA titles.
Basically, i have a few € laying on the side and i wonder if buying a another R9 380, exactly the same make/model, would benefit me at all, other than please me aesthetically (which is mostly the reason im even thinking about this), and since the HAF X is possibly one of the biggest casses ever, it would be a shame if it had only one GPU in it, right?
Im not expecting any huge performance difference, actually i dont think im even gonna get 5 more FPS in games by doing this, but lets just say it will serve more of a aesthetic purpose, than to be of use performance-wise.
So, is CrossFire even supported in 2023? Do i need a CrossFire bridge? (Idk if that even exists)
Anything i should know/be aware of? Other than increased TDP obviously.
Cooling the system with 2 GPU's won't be a problem, at all.
Keep in mind i will soon be upgrading everything in my system other than the HAF X case, so this build will serve me for around 6 months more, so its just a little "looks" upgrade.
Thanks in advance!
 
I ran Xfire back in the 2500K and 6970 days was decent then but it's worthless now for gaming, been dead for a good number of years.
Yeah, i read abt AMD cutting of support to XFire back in 2017, which is kind of a shame, at least it looked cool having 2 or more GPU's in your rig, but its understandable since today a single gpu is more efficient than multiple, both from a performance and budget perspective
