I have a late-2011 15" MBP (see my siggy for specs) and considering that it's soon turning 5 yrs old I've been considering selling it off and buying a new one -- especially since I read that these 2011 MBPs are pretty much like a time bomb due to their faulty GPUs, so I'd rather sell mine than risk the logic board failing. 95% of the time I have it hooked to my Dell U2311h monitor, so sadly I wouldn't really be able to enjoy the benefits of the MBP retina display. I mostly use it for browsing (lots of tabs), iTunes, MS Office, some music and photo editing (nothing too hardcore), some occasional gaming etc. I'd like to buy something sort of "future-proof" I could easily use for the next 5 yrs and considering that these new MBPs have pretty much no options for upgrading the RAM, SSD etc, I'd go for something bigger from the start: so I've been looking at one of those options with 16GB RAM and a 512GB SSD. However, it seems there are two options in terms of GPUs: either with integrated graphics only or with both. Is that correct? It seems that those with both GPUs can't be had for less than $2000, though, which is too expensive for my budget. But then again it doesn't seem to make much sense to choose the one with integrated GPU only, does it? What would you recommend? I think 16GB RAM and a 512GB SSD are a must, esp. since my current 8GB RAM already often seem like 75-80% used (according to iStat menu) and would rather have more than less. Plus my iTunes library is 160+ GB big, so 256GB SSD is a no-no.
