So 7990s are going for just under $700 AUD at the moment. And my 2 7970s are coming close to being 2 years old, and are starting to degrade in performance and overheat on simple games. With AMDs new card line up is it worth buying 7990 or waiting for AMDs next dual chip solution? The x280 has similar performance to a 7970 so I'm thinking I just go with a 7990. I tried going with Nvidia but with 3 faulty 780s sent to me in a row. I've lost all faith in Nvidia to provide a working card and asked for my money back. Im idling @ 60 degrees celsius right now. Its frigging ridiculous.
