Get a GPU or if that is not in your budget an A10-7850K. Fewer things are CPU bound than GPU bound these days.
Yeah I don't know what the hell this guy is talking about, an i5-4690k and it's onboard graphics are probably overkill already. My 3570k streams 4k@24hz over HDMI on a z77 chipset with no issues.
An SM951 is the epitome of consumer SSD performance and is the fastest boot drive if you want low boot times, but with a 4690k and at least an 850 EVO or MX200 or other high performing x2/SATAIII drive you're only going to see differences in benchmarks, i.e., you probably won't notice anything to the naked eye.
If you don't do any video editing, graphic editing, MATLAB, AutoCAD, etc., and you only use your computer for productivity (web browsing, multimedia, word processing, etc.) all you should be worried about is part fidelity, longevity, and efficiency. To a lesser extent heat.
I would actually recommend an i3-4170 in this scenario as it only uses 54 watts and is a much more stable solution. Use quality RAM kits, RAM is the most likely to fail especially on an Intel 9 series.
This is an incredibly good MOBO, especially for the price. It will offer Hi-Fi sound that beats a lot of dedicated sound cards, and network drivers normally only offered at a premium. On top of that it has a really high quality and efficient design with quality parts, it's the most efficient Z97 m-ATX board by far.
