Hi All
I started mining 2 days ago and this is my very first post.

I use:
AMD A10 6300 @ stock clock, 3 out of 4 cores mining XMR @ 45-47H/s with Claymore_Old on MinerGate pool.
Radeon RX560 4GB OC @ 1970 mem clock mining 8.8 MH/s with Skunk (prospector) on NiceHash pool
Radeon RX560 4GB OC @ 1970 mem clock mining 8.8 MH/s with Skunk (prospector) on NiceHash pool
Boards are on the Mobo (ASRock FM2a75 Pro 4 (4x PCIe)
Mining alternative: 290H/s on XMR on each card on NiceHash
8 GB RAM
120 GB OZ SSD
400w PSU
This is just an old gaming rig with 2x 560 I bought for mining purposes, to learn what all this is about.
I have limited cryptos knowledge.

The temperatures are nicely low.
CPU runs at 50-51 celcius (only 3 of the 4 cores mining, it reboots otherwise).
GPUs at 55-57 celcius for the card next to the CPU and 52-54 for the other one.
I have them on a regular ATX case with open side.

I read nicehash had some issues a few weeks ago, and I don't know what other pools/miners/systems/wallets/etc to use.
After a few days of reading I made 2 wallets on 2 different places, and I am mining into them half-half.
I have not been able to mine Etherium since NiceHash says equiash and daggerHashimoto has lower returns on my system at least right now.

So my questions are:
1) Nicehash says I will mine about 16-18 USD per WEEK depending on the algorithm. Is that acceptable these days for my setup?
2) I have another 2 PCIe on my Mobo. Should I buy a better PSU (600w?), add 2 more rx560, and rise everything?
3) I use stock roms on both RX560. Is it worthy to use a modded rom? Will the extra returns compensate the trouble/time/risk/heat/power?
4) Should I abandon NiceHash and mine with another tool/pool/etc? What do you guys mine on a 4G 560 currently?
5) PLEASE PM me any first week advice you may have.

If you need more information or screenshots I will be happy to provide.

Thank you all :-)

The RX560 will take, when mining, about 100 Watts. Allow about another 100 Watts for everything else (mobo, hd, fans, etc). So a 4x RX560 rig will require a minimum of 500 Watts, so a 600 Watt PSU should do.
Depending on the quality of the PSU a 600 Watt one will do, but a cheep 600 Watt PSU is false economy and may not handle the initial startup current surge.

Ethereum mining is no longer an option (AFAIK) for 4GB cards, so pick a coin than needs less memory such as Cryptonight (aka Cryptonote) coins like Monero, Electroneum, Sumokoin; there are other coins that you can mine on 4GB card - Google is your friend.
Claymore has a Cryptonight miner, sometimes the earlier version work better on older cards https://bitcointalk.org/index.php?topic=638915.0

Mining Pool Hub is a good pool to start out on as it has lots of coins to pick from and good support

If you want to mod the BIOS have a look here to see if there is one for the RX560 https://anorak.tech/
