Just read on another thread that AMD is dropping prices. The 7970 is a bad a** overclocker. You can hit 1125MHz and 1575MHz and run stable with no voltage increase. It also runs cooler than the 6000 series. Get one with a non reference cooler and you can expect to run in the low 60's while benchmarking at max overcock. I would take a 7970 over two 6950's but that is my opinion.
