So questions. I am new to cryptocurrency but not to IT. I started doing some mining on my gaming PC and decided to invest in a second GPU to increase my mining. I am really doing it to get familiar with the process and to exchange/sit on some coins. I had some questions about the PCIe USB risers. It looks like they drop the x16 slot to x1, I assume this decrease in bandwidth does not impact the GPU calculations/mining in anyway, is this correct? What is a good manufacture to use if I wanted to pick up one of these risers? Does anyone make external GPU chassis with additional cooling/power?
