So, at the moment im stuck using a budget HP laptop from 2010 or so. Im looking into mac laptops (which will be complimented with the full size ipad) to be used during a variety of settings. I'm in school right now, so the typical work and relaxation requests are standard, but I am also starting to look into creating 3-models, photoshop, coding, selling stock, and relaxing a little bit more with some StarCraft 2 (native res and medium settings). So i was wondering if this old quad core macbook pro with the 6490m is a good buy for my requests as well as the price (it's pre-owned from Micro Center... if available, ill buy their extended warranty, an ssd, and more ram). but what do you think? is this a good buy or should i save up for a 15" retina? I would almost hate buying a refurb macbook pro retina just because i cant justify the price increase for components I wouldnt really ever max out at anytime (aside from pushing SC2). so, what are your thoughts?
