This will be my main machine and I compress a lot of video to MPEG2 and MPEG4. I am not a gamer at all. I WILL be overclocking on air only. The machine must be stable, so I won't be trying to get the greatest overclock ever, just close to it. 
I have decided that the e6600 is the best chip for my budget. Now I need to decide on a motherboard and memory. I am considering the Asus P5W DH Deluxe for the MB, but I have no need for dual video cards. Is there a better board for my purposes than this one?
I have been trying to figure out what memory will be best to use in this or a similar board. I see a lot of people using the G.Skill (2x1gb) (pc2-6400) F2-6400PHU2-2GBHZ memory, but I also see people using OCZ OCZ2P800R22GK memory and other makes as well. I will have 4GB of memory in my system. What really works best, especially in a 4GB setup?
I am also interested in why you think a certain setup is the best, so I can understand your reasoning. Thank you for your suggestions.
