Hi everyone, I’m Jimmy and I’m posting this because… well I have to if I am to post anything else. I am very new to mining so I may ask some stupid questions and such. So yeah…

@RIPPEDDRAGON My laptop uses approximately 90 watts. So basically I just need to find the hashrate of the GPUs that I want to put in the rig and put everything into a calculator and see which turns up with the most money earned, right?

I am wondering if it is actually worth it to buy a better GPU. I currently mine on my laptop(GTX 950m) which gives about 130 KH/s. I am thinking of either buying a used Radeon HD 7950 or a Radeon RX 480 when it becomes available again. To save money, I’m thinking of mounting the GPUs on an old desktop I have. However, the desktop uses 200 watts before adding the GPU, so I’m not sure that the GPUs can make up for the power costs(electricity is 16 cents/KW). Also, is there any difference in mining performance between the RX 480 4GB and the 8GB version?
