As you can see, people are lazy and dont give any feedback here, however I asked them many times. Coindata Twitter can give you some information how the system works.
Not really it only supoort 2 GPU's and CPU is too power hungry and powerful. Besdies you will need new PSU for minning with 2 gpus. Is this rig given to you for free?
Either wait for Vega and new Nvidia cards early next year. For buying or dropping price of current cards. Or look for 280/280x/380/380x 285 sometimes go cheap becuase of lesser know cards. In eBay. IF you have low electricity price then 290/290x/390/390x.
Just read about free power so yes get used 290x or 390x. Just pick up from individual sellers and not alredy mined cards. Also don't forget to check ebay.de as German site some times have better price than UK one. Buy on bidding not buy it now, but don't wait too long if you have free power.
About PSU"s. It's cheaper to get 2x750W usually, then one big one.
