2 GPUs on a ASUS B650M-A WIFI II

I work as a software engineer and I have a RX 6750XT for gaming, but recently I've been receving requests for AI applications that I'm quite unable to run locally because I don't own an Nvidia GPU.

My motherboard is an ASUS B650M-A WIFI II, it does have 2 PCI x16 slots, and since I'm quite happy with the performance I get from my 6750XT, I was thinking in buying an Nvitia RTX 4060 or 3060 even, a cheaper RTX GPU just for AI training locally.

What do you guys think? Would I lose any performance in gaming? I would like to avoing switching GPUs and I've got a 850w PSU that prob can handle both at the same time just fine.
Also selling my AMD and using the extra money to buy a 4070 or something is our of question, I live in Brazil and anything over a 60 model gets really expensive here.

My setup currenly is:
Ryzen 5 7600 (water cooled)
RX 6750 XT (oc)
32GB RAM
850W PSU (80+ gold)
1 SSD 2TB gen4 NVME
1 SSD 1TB gen3 NVME
1 SSD 1TB sata
1 SSD 500gb sata
