Question Have 1 Rx 570 (8gb), should I uprade to new card or add another 570 in sli

[floatyghost]

My system:
Ryzen 7 1700 oc'd water cooled
16gb 2666mhz vengeance
Rx 570 MSI OC armour 8gb
Asus TUF b450 plus
So should I just wait and buy a more expensive GPU like Radeon vll or buy another identical 570 for like $150. I use for autodesk inventor/ premiere pro and gaming.

AMD cards only do Crossfire, Nvidia cards only do SLI when using multiple GPU's of the same version. What is the make and model of your PSU and how old is it? I would personally ask you to buy the single most powerful card your wallet will allow and one which wont hamper the PSU's output.

FYI, always list your specs like so:

Motherboard:
Ram:
