Building a Monero rig,newbie here

[TheBeardedBaby]

Hello and lets get directly to the point.
I have some old hardware I would like to use in mining Monero.

At the moment I have the following:
GPUs: 2x gtx 560ti, 1xgtx590 1X gtx770 4gb 1x AMD 5850, 1x AMD 4850 1xAMD 7950
CPU + MBs : AMD FX8350 + Sabertooth 990fx r2 , i7 2600K + Asus maximus iv extreme z
PSUs> Corsair 650w , Coirsair 550w gold 80 , Corsair 550W

Have enough RAM, HDDs, SSDs, Coolers, and other components. I have ordered an adapter to stack two PSUs. I will order some PCI riser as well.  

At the moment I was mining with the GTX770 + FX8350 + HD5850 + i7 2600K ~ 1000 H/s / also using them for heating now in the winter but they are not working 24/7. Have to mention that I was using MinerGate .  I think now im gonna build a one miner to put in all the old hardware.

Power costs are irrelevant at the moment.

So here some questions:
1. Which MB to use for mining of the once I have now?
2. Can I mine with GPU + CPU ?
3. Can I mine with NVidia and AMD in the same time?
4. Which software to use instead of MinerGate which will allow me to mine with all the cards
 
Any suggestions are welcome

1. Which MB to use for mining of the once I have now?

Wow, that's something a gaming board you have, honestly I don't have or use those boards but what I usually do is that I look for possibility of more PCI-e slots that could support more GPU's for mining.

2. Can I mine with GPU + CPU ?

Yep, this is possible, just look for a miner that supports GPU and CPU mining like Claymore and run 2 instances

3. Can I mine with NVidia and AMD in the same time?

Yep, however its a bit tricky on mixing those 2 type of cards, but Claymore miner can support AMD and Nvidia simultaneously.

4. Which software to use instead of MinerGate which will allow me to mine with all the cards

As stated above Claymore also can do this.

1. MB that has a lot of PCIe for future expansion.
2. Yes
3. Yes
4. you can use XMR stak or ccminer/sgminer

Thank you for the comments, It is a bit more clear now.
 
As I said earlier I have a lot of parts laying around, which don't cost anything to me. 
So any suggestions are welcome

Do the RAM plays a role in the whole ting? 16/32/64 GB what is best?

Regarding the MB, which one to choose now? Here are the specifications:
 
https://www.asus.com/ROG-Republic-Of-Gamers/MAXIMUS_IV_EXTREMEZ/specifications/
4 x PCIe 2.0 x16 (x16 or dual x8 or x8, x16, x16)
1 x PCIe 2.0 x4
1 x PCIe 2.0 x1

https://www.asus.com/us/Motherboards/SABERTOOTH_990FX_R20/specifications/
3 x PCIe 2.0 x16 (dual x16 or x16/x8/x8)
1 x PCIe 2.0 x16 (x4 mode, black)
1 x PCIe 2.0 x1

Asus maximus iv extreme z has more PCIe slots so maybe its gonna be better.
I have 2 other MBs with i7s 1st gen.

Other think to consider, if I stack 2 PSUs , 1x650W and 1x550W = 1200W will be enough to feed the 5 cards?
Can I stack one more 550W in
