Hallo! I am going to upgrade my Mac Pro early 2009 4.1 (Nehalem 2.66 quad-core). Using 6GB RAM so far I want to go for 12 or 24GB RAM at least. Not using VM or stuff like that. Most time Adobe CS5 (Photoshop, sometimes Premiere Pro). Do you guys think, that 24GB (3x8GB) would be an overkill and 12 should be enough at all? I would not mind the difference in price. Here you can see prices of RAM sticks in Germany: klick. They should all work well. Even 3 of the 8GB sticks as I read the last days. Further more I want to go for a SSD - having OCZ Vertex 3 or Crucial M4 in my mind. Knowing, that my Mac Pro has SATA2 only and that OCZ Vertex 2 or Agility 2 might do a good job also. I found some articles who said, that there might be some benefits by using the first ones (Garbage Collection, TRIM-Option). Want to have 240/256GB versions. Have a RAID0 with 3 HDDs on my system right know, but had some difficulties with Lion during the installation. So I want to put the OSX and other software on the SSD and let the data on the RAID0 only. Wanted to do that all in December. But know I found this posting in an other thread: klick. Price cut. Don´t know, if I should wait a little longer with the replacement from the SSD?! Suggestions to this upgrades are very welcome. Thx.
