Gainward Phantom GTX570 Review
Far Cry 2 relies so heavily upon pure performance thanks to its console heritage and use of the earlier version of DirectX that both the reference and Gainward designed GTX570s are a gnats chuff apart at all times. Only when overclocked does the Gainward sneak a frame or two but as we're long past 60FPS it's not a major difference.
Metro is a supremely harsh test of any system and to obtain 60fps demands two GPUs. At stock the Gainward Phantom GTX570 just lags behind a little, but makes it up when overclocked. Given the stressful nature of Metro the odd frame differential here and there is to be expected.
