Hey, I've got the Mac Pro 3.1 2.8ghz quad core x2 and had been holding off on upgrades for awhile in hopes of a more conservative mac pro uograde by Apple. Seeing how that's not the case, I have started maki some upgrades to my machine... bumped the RAM from 6 to 8 gb, replaced the stock card with the 5770 and I want to do more but thought I would check in first. I was wondering if you can buy the heatsinks for the ram separately so I could buy cheaper RAM and then just clip pn the heat sinks myself. Also, it seems manageable to upgrade the processors however I am unclear which ones to get. I am thinking if I could go to 3ghz instead of 3.2 that would be best seeing how from what I have found the extra .2 ghz is quite a leap in price. Is ebay the only place to get them and can I get one that says it was manufactured by dell if all the specs are the same? I am confused. Even though all my drive bays are full, I would like to add an SSD drive... I am thinking swapping put one of the two optical drives for and SSD seeing how I rarely use my optical let alone both of them. Then I would like to make use of those two unused sata ports, anyone recommend a good PCI Card for this? Any advice would be great seeing how I think I am committed to sticking with my 3.1 until Apple stops including it in updates and even then I will probably wait another year. Thanks!
