I have an i5 3570k O/C @ 4Ghz, 16gb of 1600Mhz ram, a GTX 780 O/C @ 1.15Ghz & stock memory speeds, and finally 9.06 Mbps download & 0.72 Mbps upload speed. Will I be able to run a two person, and maybe more people in the future, server on Tekkit Classic? + I need help getting my friend to join as we are both in the same hamachi group but he can't join but I seem to be able to play it?
