While you can replace the motherboard depending on the price of the board and the machine, it's generally not cost-effective to do so a lot of the time. You can snag good ones with the R9 GPU for $400 today all day long to the point it's purely because of the Intel fire sale. The prices today are tempting me to snag a 2nd 2015 DG Retina and I'm not particular about the CPU speed between the 2.2 and 2.5; if I end up with a 2.5, I'm happy but I'm also happy with the 2.2 since it's not far off.

That said the difference between the 2.2 and 2.5 boards is minuscule; they both have the same GPU, and 300MHz will make little to no difference in performance. if you can get the 2.5 board at a very agreeable price I see no issue but I would not spend a lot more to get it, especially with how plentiful 2.2 boards are which usually leads to a more agreeable price for the part.

There are 2,8 boards out there too, but those are rarer then hens teeth; if I was on the market and it had the GPU AND 2.8 i7 I'd take it home; yeah, not much faster then my 2.2 but especially if it shipped with the 1TB SSD out of the gate?

Orange is the GPU (will need to be replaced, or you need a motherboard) and the red part is the CPU+IGP, hence the split dies.
As far as replacement goes, match your old board OR buy the board you want, but you need the matched heatsink if you upgrade it from an IGP to IGP+GPU machine, for example.
