We're trying to build a gaming/ audio recording pc for $500. When we reached the topic of GPUs, we learned that you could run 2 GPUs in tandem with each other, which would give you better graphical capabilities than just 1. We did do some research on running 2 GPUs and the advantages and disadvantages of both options. after acquiring the information on GPUs, we do not know which one to choose. any suggestions? Thanks in advance!
