That is typically a big plus - especially if you use Windows. It is in fact probably the single major reason to pick a MacPro today, although I would probably rather get an iMac in that case.

I don’t have any hands-on experience with the new MacPro but its specs are underwhelming. It is an experiment - if you can leverage the GPUs for computing, then it may be worth it, but it’s still quite hard to do so. With AMD you’e essentially stuck with OpenCL and other than core support so you can write your own kernels, there is very little else in R to leverage that. Today, you’re much better off getting a server/workstation which you can load with RAM and more cores for computing for the same price (running Linux, obviously, you really don’t want to do computing on Windows with R) - and use your desktop/laptop just to access its computing power.

I also do quite a bit of work in QIIME - which can be done on the mac (not the PC) and is both RAM and CPU intensive... so, I can benefit from multiple cores, large RAM, etc.  My 2011 MacBook Pro seems extremely sluggish at this point when running basic tasks (probably need to do a fresh OS install),

If you encounter sluggishness in OS X is pretty much always a disk issue. Wipe the disk or even better put in a SSD - it’s more than worth it - a whole different world.
