What am I losing by going with Z87 over Z97?

Long story short, my current Z87 board died and I need to a replacement ASAP. I was originally going to go for a modern ASUS Z97 board, but I am seeing Z87 boards dirt cheap after MIR.

What am I losing by going with Z87 over Z97 other than SATA Express/M.2 support? I am running a 4590K so I assume a BIOS flash will be required since the 4590 was a "Haswell Refresh" but I have an i3-4130 that I can pop in for BIOS flashing purposes.

In other words, should I go with the cheaper Z87 board, given that I don't give two hoots about SATA Express/M.2, or should I go with the Z97. Oh, and I have no intention of upgrading to Broadwell-K when it comes out either.

Depends on how old the mobo is or how long it has been on the shelf as to if you'd need to flash it first. I'd imagine most would have a compatible bios already installed by now.

I'd say z87 given you don't care about m.2, broadwell etc..

Z97 has the most updated feature set and will allow you an upgrade path.
