hello everybody, here's my current desktop config,the problem is when i put my graphics settings in GTA IV at
maximum I face some deadly hitches every 1 minute and it keeps hitching for 20 seconds although i play with 1366*728 resolution (an 18.5 inches LG) i don't expect this cause i've never seen like this on Crysis2 (DX9) or Assassins Creed brother hood at max details.
--Where does the shortage come from? PS,CPU, GPU ,RAM or hard drive?
--Do I need an SSD or a WD Caviar black to get the maximum details on almost every game at 1366*728 without problems ?


prethankses for your help :D
