I just bought a 50" LED 120hz. Moved up from a 32" 60hz and man ... It is a whole new game. Its been a little over a week and I'm still having trouble getting my crucible skills back. The reticle movement just feels so different with the larger screen and smoother movement with the refresh rate. I used to be a pretty good sniper and now I'm pretty mediocre. I adjusted my sensitivity just a bit which has helped but I think it'll be a little while before I'm back to my old skill level.
