hi folks, seeking advice for my iMac (21.5-inch, Late 2012) running 8gb ddr3 ram. The machine has become barely useable it is so slow. I understand upgrading the ram on tis series iMac is quite daunting but Im confident enough if I need to I can do just that, but I feel the issue may well lie with the HD rather than ram (I know Ram would help though) my initial thoughts are to change the HD to an SSD drive in the hope that this would alleviate some of the issues Im having, would anyone advise if this is a good idea or am I barking up the wrong tree. I run a small home printing business and running Photoshop can be highly tedious , any help much appreciated. Thanks
