Radeon HD 7770 Crossfire Game Requirement Analysis
Radeon HD 7770 Crossfire is a solution of two Radeon HD 7770 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 7770 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up around 55% better a single Radeon HD 7770 performing by itself but at times (depending whether or not the 3D game supports crossfire or in the graphics driver) it performed worse than a single Radeon HD 7770. Expect this combination to draw up to 160 Watt though the average power consumption should be slightly lower.
Most demanding games will run at the highest settings.
