There is no PC that can run Crysis on Ultra High and all settings to full at 60 fps regardless of price, it is too badly optimized.
A steady 60 fps is almost impossible even years down the line; I play Half-Life 2 at 55-60 fps on average and that is a game from four years back that was not even very hardware demanding for its time.
Even on 1024x768 with no AA or other effects it is hard to climb above 65-70.
These mythical PC for a few hundred bucks that can run Crysis with max settings do not exist, simple as that (cue someone to link to Tom's Hardware, neglecting the fact that they did not have all the settings to full, just the overall quality bar that defines sharpness, texture size and level of detail not to mention the fact that their fps averages were quite poor on all resolutions).
