My SC+ OCs particularly well, but it does use a custom BIOS. If I were to get my hands on a Classified AND it performs a lot better, I might sell the SC+ and try to get another Classified. But in the meantime, I'd run these in SLI. If it turns out to perform about the same as the SC+, then I would just keep the SC+. I've never really messed with those super high-end cards though. It'd be worth a little extra money to play around with one for a bit. But I'm skeptical that I'd get a massive performance difference using a Classified on air. Those things seem like they're meant to be water\ln2 cooled. Even if they are binned chips.
