thanks for the tips,
I was thinking of tryingto start with a 570 or a 580, then eventually snagging a 5700 or 5800.
Back when I was researching gpus everyday, SLI was still newer and people had a hard time putting different gpus into the same system, has that been solved?
This can sound crazy but it's true presently I am using a RX 5700 and a RX 580 in a single motherboard and no problem so far in fact I have another motherboard that I built with few NVIDIA graphics card mixed with AMD graphics card and no issue so far if there is any problem all you have to do is switch the risers indifferent PCI slots and it will work
