I purchased an EVGA GTX 660 from newegg during their new year's sale, but now I'm looking to SLI. Preferring to pay with cash this time, I looked to a local store that would price-match, but they only carry the superclocked edition. Would anything go wrong if I SLI'd the regular 660 with the SC'd edition? I know it's the same chip, but I'd rather be sure before purchasing.
