Hi, I know there were tons of threads like mine, but I still need your help guys! I'm looking to buy a used MacBook Pro on eBay and here's what's in my price range: - Early 2013 2.4 or 2.7 GHz rMBP w/ 16GB RAM and dual graphics (Intel HD 4000 + GTE 650m) - Late 2013 2.0 GHz rMPB w/ 8GB RAM and the single Iris Pro GPU I mostly use my computer for internet, Office, etc. (75%) and I also use (in order of frequency): Photoshop, Sketchup, Logic Pro, Premiere Pro (25%). 95% of time I run my MacBook connected to a 2560x1440 monitor. I know the late 2013 models have Haswell processors, faster SSDs, great integrated GPUs and better battery life. However, "on-the-run"-performance" isn't important to me, neither is battery life. I'm connected to an external monitor all the time, so I'd use the discrete GPU all the time anyway. Late 2013 model doesn't give me a choice (at least not in my price range) - I have to use integrated graphics. Wouldn't I benefit more from the early 2013's discrete GPU? Or do the late 2013 model's offerings still make it a better performer, even in my case? Thanks! EDIT: I have 16GB of RAM installed in my current MacBook, which would make 8GB a downgrade... But I don't really need 16GB, do I?
