So my 2010 mac pro is a solid beast, and is working well for what I use it for (some gaming but mostly as a photography workstation and a home development machine (VS 2012 builds faaast on this compared to my work Dell laptop). I'm about ready to pull the trigger on some upgrades and was wondering if anybody has experience with these parts and/or suggestions on alternatives. I'm budgeting myself for about $500-600 but that is flexible. Currently have: 2.8 GHz Quad 3GB 1066MHz DDR3 Radeon HD 5870 Standard 1TB Hard Drive Buying: 24GB RAM OWC85MP3W8M24K $221.99 Desktop SDD 1 (System) OWCSSDMX6G120T $149.00 Desktop SDD 2 (Aperture) OWCSSDMX6G120T $149.00 SSD Mounts x2 OWCMMP35T25 $39.98 All part numbers are from OWC (macsales.com). My thought is using a new SSD for my system drive (which also hold my Windows partition), a secondary SSD just for my Aperture library (which will be partitioned to reduce overall size... currently about 200GB), and keeping the platter 1TB for general storage. I'm starting to run into bottlenecks in memory when using Aperture (excessive swap file usage) and hard drive access times are getting pretty appalling when scrolling through various libraries.
