About a week and half ago I was going to buy the gigabyte r9 285 for $170 after rebate but since the new 300 series was coming out I decided to wait. I know the r9 380 is a rebrand r9 285 with a higher clock speed. I was wondering if it would be worth it to squeeze in the extra $30. I want to save as much money as possible. So which one should I get? What does the r9 380 have (besides a higher clock speed) that the r9 285 doesn't?
