Radeon HD 4870 vs Radeon R9 270X
In this comparison between Radeon HD 4870 and Radeon R9 270X you will find out which graphics card performs better in today's games. Bear in mind that third-party versions may have more efficient cooling and higher clock speeds. This will increase cards' performance, though not by much. In addition to raw power you should also take into account the dimensions. Thicker models simply will not fit into a small mini-ITX case.
