I was thinking of getting a Z97 motherboard to go with an i3-4130 for an office pc running Ubuntu. Does anyone have a recommendation - I was thinking of maybe getting a Gigabyte GA-Z97M-DS3H.
I think your plan is good.
You might get a lower price with a H97 based motherboard.
But... I like the Z97 which offers you a future upgrade path to 14nm broadwell or a overclockable "K" cpu.
I can't talk about Ubuntu issues.
Thanks for that link... I was struggling to make sense of the different gigabyte Z97 motherboards but that comparison page made it so much simpler for someone like myself who isn't used to buying mobos.
