Ocaholic posted HD 5870 vs HD 7970 - Should I upgrade?
A quote from the article:
The AMD Radeon HD 5870 is definitely still running in many gaming rigs and despite the fact that we are looking at a graphics card that is now three generations behind, it still holds its ground in many games, at least if you are not pushing UHD resolutions or ultra-high in game settings. Unfortunately, with latest batch of games, it definitely shows its age and when compared to the Radeon HD 7970, it becomes a rather unfair battle, making the HD 7970 a much better choice.HD 5870 vs HD 7970 - Should I upgrade? @ ocaholic
