The 5850 PCS+ is a factory overclocked model with enhanced cooler and we will be putting it thorough a selection of real world tests, including StarCraft 2, to establish how it compares to the best 5830 on the market. In addition to this we will also take a look at how both cards perform in the recently released Mafia 2 and Lost Planet 2 benchmarks before concluding with some 3D Blu-Ray playback and GPU computing tasks.
