Ethereum rig setup and information

Hi everyone,

Been reading on this forum for quite some time now and finaly dicided to create an account and jump into this blockchain world.
I was thinking of getting into Bitcoin mining, but from the looks of it and what i have read it looks like i am way to late to the party, and at its
current difficulty level and price its just not worth mining it.

For those interested in seeing the network :https://ethstats.net/

So i came accross Ethereum, and from what i can tell this might become the next big thing once the financial institutions get into it, and prices has allready shoot up to
around 11 usd. So i want to get into mining Ether , but i do have a few questions i hope you guys can answer me because it all seems somewhat. The information on how
to mine for ether is not excatly friendly for not so technical skilled people like me. So its a pain understanding it all

I believe these questions would be benefitial to other new people who wants to get into mining and supporting Ethereum
I will later create a tutorial on how to in a few steps to get started with mining with a pool using ethminer, at least i know how to do that.

Wallet/Account and moving things around :

1: So you can create a account using the ethminer.exe program, and i created one and have an adresse and the password i selected, and you can even create one from this site(although i would be vary about that, what if they registere that info and steal your account later)
https://ethereumwallet.com/beta

When this wallet(account) is created, is it then registrered somewere inside the Ethereum network and all i need to remember is my adresse and password?
And if that is the case, then what is this all talk about online wallets when you only need to remember your addresse and password and that is all you need !!!

2: I have started mininig using geth and ethminer (using my own account adresses)and mining on a pool called https://ethereumpool.co/stats/ and from what i understand they will then send the
ether i mine to my adresse that is registered inside the ethereum network. Have i understodd this correctly ?

3: Now what if i instead mine on my computer but i dont use a pool, were does the mined ether go ? and if its stored somewere localy then how can you
transfer that ether to your account. Right now i am mining to a pool using this command in cmd : ethminer -G -F http://ethereumpool.co/?miner=25@0xa745b9495b5326a7bf2d865063f24a6964295ee3@Main1

If i want to mine locally and not use a pool, does anyone here know what command to use ?
And incase you do mine locally, how can you transfer the ether to your account ?

Building a rig:

So i am pretty excited about Ethereum, and want to build a miner for it, so basicly a computer with 4 high end GPU's
I have been looking into cloud mining via https://www.genesis-mining.com/ but the numbers just does not add up for me.

It looks like AMD GPU's are more optimized for the X11 algo and NVIDA is lacking, on my private day to day i have 2 Gforce GTX 980TI in SLI, but the performance
is pretty bad. Only getting everywere from 10-15 MHZ/S . Pretty bad considering other weaker AMD Cards are getting 25 MHZ pr card, not sure if i should disable SLI
and or change some settings...but the performance is not that great.

But before i purchase 4x R9 Fury Cards i want to understand how to calculate Hash rate based on the GPU spesifications, but i cant seem to find any information about that.
And those who think they know, are just trowing numbers around without really showing were those numbers came from. If i can get decent hashrate using much cheaper card, then i dont
see the point in spending alot on high end cars when i can get the same performance on cheaper ones.

My idea for now is to learn how to calculate Hashrate based on the GPU and then build 2 computers, woth with 4 AMD Cards.
This Company(http://www.vmxlabs.com/) here is building Ether minig righ, using pretty cheap Cards (AMD R9 380) and with 6 Cards they are getting 115 MHZ/S

How on Earth are they managing 6 Cards in one rig, i thought crossfire can support up to only 4 Cards ?
Does anyone know how they are managing 6 Cards !!

I hope someone with some experience with Ether mining can give me some information, once the questions are answered i can create a newbe guide and post it here later
with a youtube video on how to setup the entire mining system and how to move Things around.

Any information would be very much appritiated

Thanks
