The gtx1660 has 6gb, if you are building a mining rig for future proof its better to buy a 8gb video ram gpu, by 2024 those GPUs with 6gb will be obsolete to mine Ethereum, that is if Ethereum POW algorithm still works
Not everyone mines just ETH though
I like to mine lower-cost and difficulty coins sometimes early on, they might get big later and you got some stock on a wallet HODLing
I'm also planning to build a 6x gpu next week, I've already order some gpu but I have a hard time choosing between gtx1660 super and rx5500xt, they are both very good for mining but rx5500xt have a upper hand because it's 8gb supported, gtx1660 super has 6gb
Its possible to reach 30.04 mh/s at 70w with the gtx1660 super doing few tricks but you can't get 30mh on a rx5500xt, the only advantage that the AMD have over the Nvidia is less power/energy consumption and the 6gb memory which can last only 4years for mining Ethereum
Thanks for the tips. I also thought best was to buy GPU's that are worth 500-600EUR, then after I learn how to build them and experiment a bit, see if I like it I could start buying €1k+ gpus.
Don't worry yourself about future proof or not, it will take good four years for Ethereum Dag file to enter 6gb size and you would have make 3x of your ROI before that time arrives, its a good buy, also less electricity power consumption is a huge plus
Thanks!
Is it a decent idea to invest in cards like 3090, once I am 100% sure I want to expand my farm?
