What would you suggest other then gpu mining?
Today bitcoins (and other coins with the same SHA256 algorithm, like Bitcoin Cash) are mined with specialized hardware, ASICs (application-specific integrated circuits). They are orders of magnitude faster than GPUs for this task, so bitcoin mining with GPUs is essentially dead (and was so for three or four years). Basically there are two options:
- Get an ASIC miner. I do not mine bitcoins since 2013 and I have no first-hand experience with ASICs, so it is better to ask someone in the Mining Hardware subforum (
https://bitcointalk.org/index.php?board=76.0).
- Build GPU rig for mining altcoins, which is no less profitable. The choice of GPUs (ATI or Nvidia) depends on the coin(s) to be mined. There are some websites for comparison, for example
https://whattomine.com/, and the Altcoin mining subforum I mentioned before.
