Hi there. I know a number of these questions have been addressed across various threads, but it's tough making sense of everything in a consolidated way, given my specific setup. So I'm opening it up to all of you for suggestions as I try to avoid having to replace my 2009 MP. First of all, my usage: General computing including Microsoft Office, iTunes, etc. Light photo work (often via Aperture, occasionally via Photoshop variants) Rarely need to do anything in video I like to keep a number of applications open at the same time to avoid having to re-launch (e.g., 8-12 applications sometimes); I do close things I know I won't need So nothing too heavy/intense, but iTunes and Aperture can be painfully slow My setup: 2009 MP Octo-core, 2.26GHz OS (10.11) is installed on an OWC Accelsior drive with more than 50% free space All my data files are on a software RAID 4 TB internal WD Black set up (e.g., 2x2TB); backed up automatically to a single internal 4TB WD Black drive and an external 4TB WD Red drive EVGA 750 (non-flashed) GPU using latest NVIDIA web drivers 32GB of RAM One 30" Apple Cinema Display One 24" 1080P (I believe, but definitely not 4K) Dell display Internal USB 3.0 card When I upgraded to the 750 GPU (got a cheap deal), that helped speed things up a bit. But the computer continues to bog down. Would a new GPU (like a 980ti) help out in my usage? Or am I stuck with a CPU upgrade or just getting a more modern machine? I like my setup generally so I'm disinclined to give up on the old thing, if I can help it. Any suggestions? Thanks!
