Hey guys
I'v been here for a long time
But most mining I did was cloud based and from my laptop/PC

So, I'm really not experienced in the field.
I'm considering investing into GPU mining
I'm reading this
http://www.coinminingrigs.com/how-to-build-a-6-gpu-mining-rig/Building such a rig would cost around 2500$ if I'm right?
Also, setting up different GPUs shouldn't affect performance?
As I see, mining ETH with that sort of rig would bring around 1000$/month
Making a break even after 3 months
What's my biggest motivator is that, even if ETH goes down, there's always other profitable coins to mine with the setup, right?
I just want some tips to see if I'm not getting ahead of myself
For the 100th time... gpu mining will die in a couple of months. Do not start mining! Nvidia and AMD will release series of gpus only for mining which will skyrocket the difficulty of ETH and other coins also. What will happen with the fork of btc? Do not invest in mining hardware you will lose your money and the market will be flooded with cheap gpus. This happened in 2013 do no relive the past mistakes.
