The 5830 isn't much of an overclocker since it has an 800MHz clock already. Still, it's not too much more and the 5830 will generally preform better. Personally though I would either get the Hawk and overclock the crap out of it, or spend a little more for a 5850.

5830 is a superb overclocker like all 5xxx series its easy to get to the near upper limit of 1ghz with pretty much any 5830 5850 or 5870 with slight voltage bump!
