I am new to mining but after reading and research I am going in with Monero. I am planning to use the Sapphire RX Vega 56 8GB GPU. The motherboard is Asus B250, 8GB RAM. The questions that I have are:
1) After referring to MoneroBenchmarks it seems that Vega 56 cards provide a really good hashrate at low power. But, are there any better options that I can consider? And, when I select a GPU, what configuration of the GPU should I focus on to know which one will be better. I know that efficiency will vary depending on the algorithm I am processing, but besides that is there anything relating to the GPU's config that I should focus on?
2) Regarding the processor, is there one that I should focus on to increase my efficiency? Since the work will be done by the GPUs primarily, so will the choice of processor play a significant role?
Thanks.
