Hello.8kx user here.I love mine,FOV is a Game Changer IMHO.I find Performance and Clarity very good as well.I do need to zoom in on some of the smaller steam gauges but I believe that's the case with most Headsets,
Looking at your system specs...I would say you'd be able to have a great experience with a 8kx.
Also...depending where you buy from you'd be eligible for full price credit towards a 12kx when it comes out using The Pimax trade in Program ,
er IMHO
