6 gpu rtx3080 hashcrack computing machine
hello, i am going to purchase 6x gpu rig for hashcat
What could you say about it? I have searched the forum and found person saying that 2080ti is the best for money\speed like 2 years ago, so that is why I've decided to make it on 3080 GPU's 
3090 has overheating troubles
3090s don't have overheating issues, the coolers on them are insanely overbuilt. As far as building a rig with 6 GPUs, it's not really so easy these days. Many of the modern GPU form factors do not lend themselves to being in such a rig.
