I have a Dell Dimension e521 project computer im somewhat upgrading. Im looking for a faster processor close to 3.0 ghz and a somewhat good graphics card. I want to be able to play DayZ. The recommended graphics card for DayZ is a NVIDIA GeForce 8800 GT / ATI Radeon HD 4850 with Shader Model 3 and 512 MB VRAM or faster. I want a processor that can handle something close to these graphics cards. I would much appreciate if someone could help me.
