H-97 can't be overclocked, and the 4790k has a 400MHz advantage in clock speeds, (4.0-4.4GHz vs 3.6-4.0GHz of the non-k) so could be a benefit in more than a few apps.
8Gb of ddr3 is kinda tight, but doable.
Considering consoles range from 30-60fps, it's not a bad deal, I game happily on a i7-3770k and gtx970, even in 8man teams, but 16 gets a little latency and 24man is noticeably chopped. So there are drawbacks.
A 9400f with b360 mobo and 16Gb of ram will run @ $300 and is pretty equitable for the most part, only having advantage due to higher IPC in games that make use of it. So for half that price at $150, the i7-4790k is still viable.
The biggest drawback will be driver support, you'll get the basics and a few updates, but 4th gen is no longer actively supported by the mobo manufacturers, so can possibly have issues with current/upcoming windows versions and some software.
