All MC methods are in general extremely CPU consuming. So, soon or later you always reach limits of your computer. From this point of view I suggest most powerful CPU you can buy by your budget + additional RAM + fast SSD disk. In some cases GPU capabilities (cuda) are very useful.
- CPU with 8 physical cores
- 32GB RAM
- SSD system system disk 256GB or more
- HDD data disk 1TB or more (7200rpm)
- NVIDIA graphics card - gpu-cuda computing
- Linux OS
