When it comes to the performance of the ATI Radeon HD 5850 we found it to be 15-25% slower than the Radeon HD 5870 in the vast majority of the benchmarks. It was also faster than the NVIDIA GeForce GTX 285 graphics card, which is currently NVIDIA's flagship single GPU video card! If we had to suggest a screen resolution size to go with the Radeon HD 5850 it would have to be 1680 x 1050 and under if you like to turn all the eye candy on. Sure, the majority of the benchmarks that we ran here today showed the Radeon HD 5850 was able to run above 60FPS at 1920 x 1200 with 8xAA enabled, but we would like to plan for the future. With DirectX 11 game titles coming out soon a Radeon HD 5870 would be the better choice for gamers with monitors greater than 24" and screen resolutions in the 1920 x 1200 and beyond range...
