Buddy of mine picked up a 5850 to replace his dual 4850 setup. His Vantage score was about 10K which is about the exact same as his dual 4850 setup but this seems low to me? He has an E7200 @ 3.6ghz and 4g of Ram on a P45 board. He overclocked 775/1100 and pulled a hair over 11K on Vantage. Does this seem right?
