Like many people intending to buy more RAM, I have a hard time figuring out when the right time to buy for my machine is. So I've got a few questions for people who already bought, are thinking of buying, or have watched RAM price trends over the years. I currently have 4x 2 GB sticks plus the 1 GB sticks that shipped in my 08 Mac Pro. I'm intending to buy 4x 4GB sticks to expand it out to a total of 24 GB of RAM, but I want to buy when it's cost effective. Currently, the best price I can get for what I want is $496 from TransIntl off of a holiday special. Here are the questions: Does anybody know what the lowest price 4 GB 800 Mhz FB-DIMMs ever sold for was? I don't think we're at the low now, but prices were higher half a year ago than they are currently. Do you think that prices will continue to trend down, or are they going to go up soon as a result of the memory being obsolete and having low production volumes to begin with? Should I just buy this now, or is it likely to get cheaper? Currently, Photoshop and Lightroom are my only apps that really grab a lot of memory (and I create some massive images), but I expect the next version of Final Cut to grab tons. Your thoughts? All opinions welcomed.
