Thanks for your reply. And you are right, neither this machine nor El Capitan has a problem with running CS5 or any of the various graphics or music apps I have. I'm not a huge fan of basically wasting my time using any of the magic video apps they keep springing on us - even though some of them are fun to watch. Graphic art is important to me so I'm trying to upgrade speed and reliability more than anything else. I'm also getting into using a Huion and speed is important to that.
Since I'm 84 and living on Social Security, I no longer can afford to buy all the latest whiz-bang stuff Apple keeps throwing at us. I wish I had a better setup but it is what it is.
While it's always tempting to own the very latest hardware and apps it always gets down to how important it is to whatever you want to achieve. My old Mac Pro early 2009 does an excellent job with both graphics and music so mainly I'd like to just max it out to be the best it can be. I'll be changing over to a 1TB SSD tomorrow. Today I hooked up a second monitor as extended and that helps in my current effort to build a website using Dreamweaver. I suppose next I will be upgrading the video card.
I appreciate any advice I can get regarding improvements to my hardware. Like best value in a video card to replace the NVIDIA GeForce GT 120.
My stuff: Mac Pro, Early 2009 4,1, 2.66 GHz Quad-Core, El Cap 10.11.6, 32GB Ram, 2TB WD, NVIDIA GeForce GT 120 1024 MB
