I have a 2008 Mac pro 3,1 It's a dual 2.8 machine, I have upgraded slightly. as she is now Dual quad core 2.8 12 gig ram4 ea 1gig from apple, 4 ea 2 gig owc Ati 4870 512 meg gpu. OS is 10.5.8 Mainly used for Photoshop and Dreamweaver,some video editing and dvd authoring . My questions for you all are as follows: I was curious as to how to get the most performance wise out of the system, I am about to do a re-install of the os and am planning on finally installing snow Leopard. Would it make sense to go with an ssd from owc for the os/application drive? (I am thinking of their 114 gig drive) coupled with a small(40 gig) ssd for the dedicated scratch disk. I would then install a 1tb partitioned into to 500 gig partitions for my data and a clone of some sort as a backup. Is there going to be a noticeable improvement if I was to go to 16 of ram? Would upgrading the video card to a 5770 or 5870 be worthwhile? Currently my main frustration is load times and performance in the adobe suite. I like the new iMacs but HATE the bs with the hd power supply. And I don't really think it would be any faster than what im using now, I'm sure there are os and ps tweaks I have yet to learn that are leaving a bit of my performance on the table...... Thanks for taking the time to read my post.
