Sapphire Radeon HD 3870

Test Setup:

As always, we did our best to deliver a clean set of benchmarks, with each test repeated three times and an average of those results is what we're reporting here. In the rare case where performance is inconsistent, we continued repeating the test until we got three results that were consistent.
