I'm putting together my first build and am looking to find the best memory to go with my processor (Core Duo E6600). I plan to get 2GB (2 x 1GB) of DDR2 memory but I'm not sure whether I should be choosing 800 or 1000. I am trying to get the most out of my processor WITHOUT overclocking. Since I am new to building my own computer I am simply focusing on pairing the best memory to go with my E6600 so any and all advice is welcome.
