I just purchased a new PC with Core 2 Quad Processor Q8400 at 2.66 GHz, 4 GB memory, 1 TB HD, running W7 Home Premium 64 bit. So far, so good, except it only has Integrated Intel Graphics Media Accelerator 3100. I will use this PC solely for business but I am in printing and will be opening large graphics files. I do not edit video or otherwise rely on any motion-intensive graphics. Do I need a dedicated GPU for general web surfing, heavy e-mailing, and typical business use? If so, which card would you recommend? I will never play games on this machine.
