I've got a 2009 Quad-Core Xeon, 2.66 GHz with 16 GB RAM and the original ATI Rdeo HD 4870 video card driving two 22" LCDs (one with Apple Mini DisplayPort To Dual-Link DVI Adapter). While it is compatible with Mountain Lion, I'm looking for opinions on possible upgrades. I hope to get two more years out of this computer. I run all of the usual office / web apps, do some light video editing work, extensive photo editing work (Adobe LR and PS), as well as several different scientific software packages (e.g. SPSS, Stata, MatLab, Geneious, Prism) and some PC-side work via VMware. possible upgrades: 1) change v-card to ATI Radeon 5770 (about $270) 2) add 240 GB SSD for system and apps (about $240) Thanks for any thoughts.
