I have a 1090t coming soon, and of course, I'm planning to push it. Trying to figure out what I want it to do. About how far can they get on stock voltage? What does it take to get to 4GHz, and what kind of cooling does it take to keep the temps down? What's the max safe temp? About where can I expect to find the 'sweet spot' where it runs reasonably fast but without a super increase in voltage?
