I recently got a 4850 and was looking at the clock rates... tuned them up a little and got to 675(700 max) for the GPU and 1150 (1200 max) for memory.... then i went to newegg and noticed 4850's for sale had a lower core clock (625) but the memory clock was almost double mine (2000)..... am i missing something?

At 1150, you have an effective memory clock of 2300MHz. It's double data rate, so there are actually 2 transfers per clock cycle.

not trying to make you feel worse, but the auto tune got it up to 1185 i think and i actually brought it down, same with the core... its the stock cooling system but does not seem that it created a lot more heat
