got the ram for my g5 and it runs much quicker, i noticed when i took out the old ram chips they were so hot i couldnt hold them for more than  a few seconds without burning myself, and the G5 processor houseing i couldnt touch for more than a second. i actually leave my imac ON all the time cause someone told me it lasts longer, and that shuting down or putting to sleep is wear on the HD, anyone know if thats true? cause it gets so hot, i feel i should shut it down, esspecially on these 90degree days we've been having
