I do 3D and video, and followed recommendations by other people who use the 3D software I use.. Most people recommended Crucial, and I think Other World Computing.. I've gone with these vendors for my last several Macs (Lombard, DP G4, DP G5) and have not been sorry. I have seen the super-cheap RAM sticks out there, and tho I paid more for my RAM than those cut rate dealers sell for, I don't exactly consider myself having gotten a bad deal.. $120 – $150/stick I think is a righteous price, but I'd rather go with a dealer who many people doing demanding work recommend, and not have to futz and diddle down the road if/when that cheapie RAM heads south. nk
