What GPU upgrade will work for my system? Do I need a new PSU?

I need to upgrade my pc to be able to play Subnautica 2 with my friends. Unfortunately, the launch is tomorrow and they won't wait for long, 1 maybe 2 weeks, because we're all huge Subnautica fans and want to dive in as soon as possible.

I'm hoping that upgrading my GPU will work, but I'm unsure about it.

340 € - 500 €

Subnautica 2 specifically at good quality if possible. Gaming, working. 2k on at least 3440x1440. I am not gaming a lot these days, because I have so much work to do, so when I do, I really want to enjoy that bit of an escape.

None. Question remains whether or not my PSU can handle it or whether I need a new one.

I have read over and over again that a bigger VRAM size of GDDR6 or GDDR7 is a lot better and more future proof. So if possible, I would try to go for that.

Current specs:

CPU AMD Ryzen 7 3700X 8-Core Processor, 3600 MHz, 8 Kern(e), 16 logische(r) Prozessor(en)
Motherboard B550-A PRO (MS-7C56)
Current GPU GTX 1050 Ti
OS Win11
Monitor Xiaomi Mi Curved Gaming Monitor, 34", 3440x1440 (UWQHD), Adaptive Sync, AMD FreeSync Premium, 2x DisplayPort, 2x HDMI
PSU Seasonic Focus GX 550W ATX 2.4
RAM 16GB Patriot Viper Steel DDR4-3200 DIMM CL16 Dual Kit
CPU cooler Noctua NH-U14S (because RAM thingies were too high for my older cooler to be mounted).
Storage M.2 Crucial P2 CT500P2SSD8 500GB, some random Seasonic HDD and another SSD.

If you need any more information, please let me know.

Times are a bit rough for me in terms of budget, because I have a lot of necessary expenses for my education and not a lot of income. So the budget can't be raised. The maximum is really the maximum here.

Oh and THANK YOU for any advice in advance!
