Picked up a pair. Very sweet card when overclocked. Absolute CRAP at stock clocks. Beta driver is also garbage. Can't overclock in Xfire. :fou: Unboxing : Stock Clocks 06 @ 4.2Ghz : 900c, 1200m : 980c, 1215m : XFIRE : Stock Clocks : 875c/1250m : First Impressions : AWESOME.. AWESOME... AWESOME.. Major Props to Sapphire for their cooling on this beast. 5 Heatpipes? More then enough. At 980c/1215m and 60% fan max temps hit 54C.. 54 ****ing C. 1. This card would be amazing at 199.99 but i understand why amd priced it the way they did. 2. On stock clocks this card sucks ass but i have a feeling it's because of the drivers. IMO the stock driver blows and was designed to not allow the card to come into the 5850's range. 3. Overclocking makes it feel like a whole other animal. 4. I'm not sure if it needs to be added to Afterburner but NO voltage tuning.. Nada. Those overclocked results are on stock voltage with 20 minutes of Furmark testing. Anything higher and the driver will crash within a minute. Final numbers of my 5770 @ 960c, 1440m was 18,820 so on this setup an overclocked 5830 scores 1509 points higher.
