Battlefield 3 Beta: GPU benchmarks
GPU power is everything: Although Battlefield 3 shines with excellent multicore scaling (inherited by Bad Company 2), the firefights on typical systems and resolutions are completely GPU-bound. You'll need a high-end graphics card for fluent gameplay in Full-HD with 4x MSAA, post effects and 16:1 AF.
Remarkable: Nvidia's drivers give their cards an edge over the competition. The Geforce GTX 570 outperforms the similar-priced Radeon HD 6970 by nine percent, even though the AMD card runs faster in our overall benchmark index. Upcoming drivers from AMD and Nvidia will push the framerates by time and maybe change the current placing.
