Dell Precision 7720 - what is the best alt coins to mine that give highest ROI?

[alphaque]

hi, i bought a Dell Mobile Precision 7720 (mobile workstation)  with the following specs:

-Intel Core i7-7700HQ with Thunderbolt 3
-8GB (1x8GB) 2667MHz DDR4 Non-ECC SDRAM
- 256GB M.2 PCIe Solid State Drive Class 40
- Nvidia Quadro P4000 w/8GB GDDR5

i plan to use it to mine altcoins, may i know what is the best altcoin i should mine that give me the highest ROI, assuming i don't need to be worry about the electricity bill

i also want to know what OS and software to use so i can start mining here.

thanks
