Hi guys, can anyone tell me if i can add an aditional external graphics card for lenovo Y50(gtx 860m, 4gb). If so what would be the optimal option

None. The interface required for an external GPU doesn't have the bandwidth to make the set up useable or worth the cost. No card you add to your current set up would out-perform your current graphics card.

I agree with Wolfshadw, the y50 gtx 860m graphics card/chip talks directly to the i7 4710mq or 4700 processors onboard northbridge at PCI-e speeds. No other connections on the rest of the laptop could even come close to matching those speeds. (With the exception for the processors onboard internal cache.) For example a PCI-e v.3 has a throughput of 15.75 GB/s (128 gigabaud, 8 GT/s) where as a SATA3 has a maximum throughput of 6GB/s. I hope this helps.
