Which board for which cpu?

[kymira]

Hi guys im in a strange predicament.

I recently received 2 motherboards w/ cpu's already on them:

1. Z68 board (sandy bridge) with i5 3570k (ivy bridge)

2 B75 board (ivy bridge) with i3 2100 (sandy bridge)

Now, since its new future owners* will not be overclocking, is it a good idea to just pair the cpu+ motherboard from their respective generations?

Do the possible advantages (if any) of pairing the same gen, outweigh the disadvantages of losing the extra features of the z68 + i5 combo?

These will be going to my brother and nephew. These are their needs:

* Brother: Work stability (photo + video editing)
Nephew: School, surfing, light casual gaming (hearthstone & league).

No advantages to pairing the same gen so put the Z68 with the 3570k. Just make sure the both boards have the latest bios and they'll be good to go.
