Radeon HD 4870 vs Radeon HD 5850

When choosing between Radeon HD 4870 and Radeon HD 5850, it is worth examining the specifications of the models in detail. Do they meet the recommended requirements of modern games and software? Storage capacity, form factor, TDP, available ports, warranty and manufacturer support are all important. For example, the size of a PC case can limit the maximum thickness and length of the card. Often, instead of the factory overclocked card and RGB backlight, it is better to choose a reference model with a more efficient GPU. And make sure that your current power supply unit has the correct connection pins (using adapters is not recommended).
