Difference between H97 and Z97?

So i know that with the H97 boards you can't overclock but is there any other difference between the two?

Support for multiple GPU's. http://www.pugetsystems.com/labs/articles/Z97-vs-H97-What-is-the-Difference-562/

Z97 boards also support higher frequency RAM, going up to 3200MHz, while the H97 boards have a max of 1600MHz. In all honesty, it won't make much of a difference unless you're a hardcore video/photo editing enthusiast. You're better off selecting RAM based on timings. A lot of tests have shown the difference to be minimal in most applications.

If you don't overclock, plan on SLi or require stupidly fast RAM, go with H97. The latter also tends to have fewer SATA/USB ports, but not by much.

If you don't mind going with a MSI or Asrock board, you can get a Z97 for a desent price.

The Z series was 'supposed' to be the multi-unlockable platform as well. I believe there are a few BIOS on some H97 boards that unlock the multi but it wasn't an explicitly supported feature.
