Results: Grid 2
Grid 2 is memory bandwidth-sensitive at mainstream detail levels. Last quarter's poor memory performance at stock settings gives way to great results when overclocked, while Q3’s loose timings at overclocked settings have far less impact compared to already-good baseline performance.
The $2400 machine is up to 50% faster at Grid 2’s Ultra preset, though the slowest system's frame rate should still be fast enough for the vast majority of users. Perhaps buyers with 4K displays and 3D glasses will need the expensive graphics?
