You are talking about building a rig to mine BTC?
Sorry but it doesn't exist you can only mine BTC with ASIC units and please read the sticky thread under this section or read this quoted part below.
TL/DR Summary:
- You CANNOT meaningfully mine bitcoin with your PC or laptop no matter how powerful it is.
- You CANNOT meaningfully mine bitcoin with your tablet or phone no matter how powerful it is.
- Mining apps for your phone or tablet that claim to mine bitcoin are almost certainly scams.
- You CANNOT find software here to mine bitcoin with your PC by itself.
- You MIGHT be able to do one of the above with altcoins, but such discussion goes into the altcoin mining section.
- You CANNOT find or post software here to mine on other peoples' PC without their permission.
So you should understand that you can't mine BTC with GPU.
Since ASIC units are illegal in your area better stop mining because GPU mining is unprofitable.
