I need to upgrade my graphics card for XPS 8900, Skylake Z170, 6th gen I5. Unsure of limitations. Can anyone suggest the best card for this rig? I’m looking at GTX 1060 Super to GTX 2060 Super. Will those even run on this system? Much thanx in advance for anything you can tell me. 
XPS 8900, GPU upgrades?
