Been 4 years since I upgraded by PC. I think it's time to phase out my hardware and go for a new PC. Would it be a good idea to go for an all in one PC ? I might get a new system, tailored made for win 8. My usage is basic with occasional gaming, FIFA 13 Besides games, I want to take care of my work with Autocad and photoshop. Please suggest a system to care of my requirements..
