You just answered your own question.
And about overclocking, the same thing goes for you and the 9,000,000 others who've asked: go in 5 MHz increments at a time until you either get lockups or artifacts. The auto-detect overclocking feature in the drivers can be a good baseline, though many times it will estimate too high, so watch out.
