This is my 1st time trying to build a PC. Just got a decent tax return, and would like to start a PC building project to understand it better. I would like to go with the C2D. Already have keyboard/mouse/monitor. This machine is mostly a learning project which will be donate to parents when done, and occasional use for PC MMORP games. My knowledge for building PC is next to nothing , but trying to learn (building/OC' ). I would like to keep it in the range of $500-$700 if possible. Thanks in advance for all your inputs, time and advices.
