Comparison of 24 best gaming computers ($701 to $900), April 2011

In April's $701 to $900 gaming computer comparison chart we have 24 different desktops that are marketed as gaming computers. Most of them can easily handle modern games at decent settings, as expected for this price range. But some (brand computers) have $40 graphics cards that are almost useless for today's and future games. Not so surprisingly the fastest graphics card of all desktops is the AMD HD 6870, it is ~15% faster than HD 6850. Next best is the ~30% slower ATI HD 5770 which is 10-15% faster than Nvidia GTS 450 and ATI HD 5750. After them is ATI HD 5670 that has less than 1/2 performance of HD 6850. Anything lower should be avoided if you want to play games at highish settings. All graphics cards have ranking  next to the model number, see link below for the video card ranking list.
