I've got a dual core 2GHz G5 PowerMac with 1.5 GB of PC2-4200 DDR2 RAM in it (512MB from Apple, 1 GB from Crucial IIRC) - looking to add 2GB or 4GB more. I do mostly multimedia work on my Mac and now that I've gotten into Aperture, I desperately need more RAM. I was thinking of 1 or 2 of these from Newegg or this one from Crucial. Am I looking at the same thing (other than the fact that one is a kit, the other isn't)? I was thinking of sticking to Crucial because of their lifetime warranty and guaranteed compatability with my system, but what other (less expensive) options do I have? While my original limition for buying online was from Canadian-only stores, because our looney is doing oh so well, I can now venture out to the unchartered land of Newegg! Thanks.
