If it is sluggish on everything I might recommend an ssd although it wont make your graphics faster I have seen it done once and done it myself once and it works seamlessly. It can double your speed for opening programs and startup. This is for both desktops and laptops just to squeeze out a little more speed. I would recommend Samsung if you want this option. Next, if it is a desktop the graphics card can be upgraded. My dad has an older mac pro at his office used for heavy cs6 graphics design and he did the ssd upgrade as well as the video card upgrade and he said the results were noticeable immediately. Lastly, the other thing you could do to speed up the machine is upgrade the ram if you can to 8gb. Ask apple if this particular...
