Super computers make you lock faster, which is invaluable for using sniper rifles. EDIT: I should note that as of the 1.01 patch, super computers do not effect bay weapons, so you'd have to have the weapons you want quick-locking in your main hands. LR Uzume might have incredible lock range, but unless you're using sniper rifles that have a velocity of 1000 or more, then you might as well just use Predire. Predire and a head with 700+ camera will pretty much put its lock at the end of Seidenbaum's effective range. For Boosters, Dafeng hasn't let me down when I've put it on heavy setups.
