A 2nd gen i7 and whatever mobo they have is going to be such a massive bottleneck for any gpu after the 10 series. They need a new rig.

My racing SIM PC has a sandy bridge i5 with X2 6970 in crossfire, it runs things like DayZ and Asseto Corsa etc but yes the second gen cpu is being smashed by a current i3 with a 1650 (my son's PC) so yes time for a full upgrade I believe.
