I'm curious as to why when I mine Satoshis with the app "Bitcoin Miner" with my gaming computer I get slower or = to the hashrate that my older laptops are getting.. I assumed it would be 10x faster than them. Currently all 3 are doing about 18-20 kH/s. I know this is a waste of time nowadays, but still wondering why its slower?! Much better processor and much much much better video card than them. Obviously I'm very new to this and any insight is appreciated ^ ^ Considering upgrading to a few dedicated systems to mine, just trying to comprehend the basics 1st!
