Kinda excited for my new pc! I would love to try bigger models now! Asking you all for suggestions

Hello there!
Finally I've decided to upgrade my old pc, ended up rebuilding it from the ground up (case included). I'm (im)patiently waiting for all the parts to arrive!

The specs are:
-Ryzen 7 9800X3d
-2x64 gb 6400Mhz DDR5 ram (I can't fucking believe how the prices for these bastards have inflated, God.)
-Asus x870 Max Mobo
-1300 PSU
-couple of 2tb M2 SSD
-2x old RTX 3090 ROG strix

It's slightly future-proof (aside for the two 3090s) and the ram could be maxed out at 256gb.

Now I can try bigger models, would love to know what can I fit inside this machine, even quantized. My goals are mostly rp\erp with image generation\editing (possibly with qwen image\qwen image edit or chroma. Any suggestions?
