At 1920×1200 this setup was badly GPU bottlenecked so there was practically no difference between the two memory kits. At 1280×1024 though the load on the GPU eases up and the modest bandwidth advantage for the OCZ Flex II PC2-9200 kit slightly edges out the OCZ Platinum PC2-6400 kit.
This graph isn’t truly indicative of what this kit is really capable of doing. I say this as the 1333FSB on this processor is severly hampering performance. Click to the next page to see what this kit really does with a proper FSB.
