So I've been plugging along on my mid-2009 MacBook Pro (3.06 GHz Intel Core 2 Duo, 8 gb RAM, NVIDIA GeForce 9400M 256 MB graphics), but it's gotten to the point where it just can't handle the things I'm trying to throw at it. I still run VW2015 because 2016 just won't run briskly enough (haven't even attempted 2017). Not being able to upgrade the operating system past El Cap is the final straw - it's upgrade time.
Now that new MBPs have been announced, I'm looking at possibly snagging one of last year's models for a little less money. However, the mid-2015 models Apple still sells have only the integrated Intel Iris Pro graphics, and that worries me from a rendering perspective. (I draft mainly in 2D but occasionally draw and render in 3D, and I'd like to do more of that - my current machine just can't handle it). It appears I can still order a mid-2015 machine configured with the AMD Radeon R9 M370X graphics in addition to the Iris Pro, and I'm assuming that would be the better option, but I don't really know enough about how these GPUs work to understand how much I need. (VW is also only part of what I'll be doing on this machine - I'll need to render in After Effects/Motion, FCP/Premiere, and run Photoshop and other graphics/sketching programs.)
Do I need the additional graphics card? Do I need to max out the CPU? Do I just need to bite the bullet and go for the 2016 hardware? I don't know that I can reasonably expect to eke 7 years out of the new machine like I have with my current one, but I'd hope it to last at least 4.
