I have elected to go with a modified Nvidia 4090 with 48GB of vRAM. However, I found a shop not too far from me within the US that makes them. It’s called GPvLab and he has a Youtube Channel where he shows his shop and the process of making the cards.
I have just gotten the card in and I cannot wait to get it slotted in my new HL15 build. I will be back to report how this goes.
