I've been racking my brain about which model to get, and I've been waiting for these updates for some time. I'm currently using an old 2007 white Macbook and desperately need to upgrade. However, I'm not entirely sure which route to go since Apple sort of went a different route with the base 15" this year. I'm essentially debating on the previous gen 15" Macbook Pro, or either of the 2 15" models from this year. Obviously, price makes me think twice about springing for this newest high end model. However, if a previous model with dGPU can be had for roughly the same price as the current base (albeit, it would be used), would it be smarter to get that model? As of right now, I don't do graphics-heavy processes on my computer, but mainly because my computer has difficulty doing things that are not considered to be graphics-heavy as is. I plan to have this computer for 5+ years (assuming the parts hold up). Suggestions?
