Hello. Im new to the Crypto Curency realm and wanted to know if my rig would be profitable in mining Cryptos like Litecoin or others.
My rig is (or will be once I build it for personal use and to use for mining as well) as follows:
Motherboard: ASUS ROG Zenith Extreme sTR4 AMD X399 SATA 6Gb/s
GFX Cards: (x4) EVGA GeForce GTX 1080 Ti SC2 Hybrid 11GB GDDR5X (Liquid Cooled)
CPU: AMD RYZEN Threadripper 1920X 12-Core/24 Threads 3.5 GHz, 180W
RAM: G. SKILL Trident Z RBG Series 128 GB (8 x 16 GB)
I am wondering if my rig would be profitable? Im not building it solely for mining, but if it would turn a good profit over time...I may let it run as one to at least pay off my initial expenses of building it...then I could use it for personal use once I recoupe my initial investment per-say.
Thoughts on how this system would do??
Thank you greatly for all your assistance to this noobie!

I get what you are saying, I have a similar setup using x399 and threadripper with 3 vega frontier of which I have 2 running and 64gb ram, I'm waiting on my openloop water cooling to be delivered and I'll add the third card. I already made a good profit on etherium to cover my fantasy computing needs many times over. I don't rely on mining for a living and my kit is tax deductable, I'm well paid so my rig is for mining and other compute hobbies, R&D etc. I mine cryptonight coins and yes you can make cash that will offset your costs although it will take many months but it depends on current prices which are lower than they were at the moment. If you treat it like a hobby then go for it, may make a few $K pa, will it make you rich, not unless you embark on a ultra high risk mining and trading strategy

PS I sold off my etherium rig for a profit when I replace r9 390's with vega's
