I have a Dell Dimension 4550-- it is a P4 2.4 GHz with 512 MB of Corsair High Performace PC 2700 memory (one chip) and I put in my VisionTek GeForce3 Ti 200 64 MB Video Card. Most of what I do is play games -- current favorite is 1942. I also do digital pictures with some editing and want someday to be able to store my Digital Video on computer and transfer to DVD (when burners get affordable). I have about $180 to spend on it and am trying to figure out if I would be better off with 512 MB more memory OR a new video card ? And if video, what should I buy ?
