1. If I'm only getting 1GB RAM now is it better to go with a 2 x 512MB kit in dual channel or just 1 x 1GB? (I may be stuck with 1GB longer than I would like!)
2. Would there be any problems from running 'untested' 2 x 1GB ram in dual channel?
4. Are there any performance hits/gains from using up all 4 RAM slots on the motherboard (i.e. 4 x 512MB)? I'll hopefully be using CL4 PC2-6400 if that makes a difference.
3. How awesome is LR on a scale of 1 - 10.
