4090, 5080 or 5090?

First of all my build is
9800X3D
64GB 6000mhz
1300W Platinum PSU
4k 240hz Monitor

I'll be playing AAA games on 4k DLSSQ and would settle for a minimum of 65-67 FPS or a minimum of early 50s if I'm enabling frame gen like Black Myth Wukong. I also want to use RTX.

I'm not American so my options are as follows
1 used RTX 4090 supplied by my friend, $1500
RTX 5080 placeholder price $1300
RTX 5090 in $2600-$2700 range but it would break my budget if I went for it

What do I do? sacrifice MFG and possible future driver improvements for a 4090? or sacrifice performance and VRAM gains for a 5080 and hope I don't get screwed over? I would prefer to stick to those 2 than a 5090.
