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, up to 40% better than a single Radeon HD 5870 performing by itself but it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 5870. Expect this combination to draw up to 366 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.
