Game Benchmarks: Fallout 3
As seen in World in Conflict and HAWX, Fallout 3 is showing an advantage for the Core i7 system, but it's somewhat meaningless as far as real-world playability is concerned. All of the systems are delivering high frame rates in this CPU-limited title.
Fallout 3 seems totally unconcerned with any extra workload that 4x AA demands, demonstrating a notable CPU limitation rather than a GPU limitation.
