Solution
When I had a Sapphire Vapor-X edition ATI 5750, I was able to have the core clock set to about 775 MHz and the memory clock set to about 1200 MHz without it getting too hot. So I would think you should be able to achieve those speeds. As for AA, I found the 5750 didn't have much power to do any Anti-Aliasing so I left it at "Use Application Settings" then I would play around with the AA setting in each game I played. The AF on the other hand should be able to be set to 16x without a problem.
