If the job you need to accomplish is running Photoshop fast, why not either spend the money that a MacBook would cost on a substantially faster used PC laptop or, well, if you don't absolutely need portability get a desktop? The 2008 vintage Core Quad Q6600-based desktops I saved from a dumpster and set up for my kids are almost half again faster than that laptop of yours. Or to put it another way, what's your budget? It's pretty easy to find off-lease 2012-ish vintage "Business class" PC laptops for around $200, and this particular model is twice as fast as your Acer. On the local Craigslist that money... well, it might get you an okay 2009 Macbook (if you hunt *really hard), or a beater MacBook Pro. (Most of the ones I see for that price are the ones with the dreaded 8600GT graphics chip.) So... I guess it circles around again, what do you want here? Something that runs an *oooold* version of Photoshop pretty well, or something that runs the Windows version better than your Acer? They're kinda mutually exclusive.
