I know for my system, I am getting 1 gig to start with, Budget, and once 2 gig sticks are at a reasonable price I'll get one of them. My mobo supports 16gigs, and that would be overkill now but once 4 gig sticks are out it'll be nice, lol. Probably 3 years 16 gigs will be possible, with only 4 slots, thats why I wouldnt buy too many 1 gig sticks now cause I will throw them away once 4gigs are out probably. IDK wat im dreaming about, lol.
