I had a gig which required opening ridiculously large XML files (metadata for music albums). Some classical music compilations (think "6 CD bargain bin" boxsets) would end up with 1-2GB XML files. Sublime didn't even flinch when opening and navigating around the file. Truly impressive text editor and absolutely worth the license cost.
