From your list, if you can pick up the i5 4690K + the Mb in MC store, you will save more for the bundle. Also if you pick the MSI Z97 Gaming 5 in the store, you can check the MB series number right the way to see you need update the BIOS for the i5 4690K or not. How to read the barcode to verify manufacture date.

Because the i5 need at least 1.2 version BIOS ( or 7917v12.zip )
http://www.msi.com/support/mb/Z97-GAMING-5.html#support_support as long as the MB was made after 5/22/2014, the MB will have the new BIOS for the i5 4690K.
For the M-flash watch the video

Or you can get the ASUS Z97-Pro with i5 4690K.
Also if you only use the single GPU you may buy other PSU, and GPU, because 750W will be overkill, check the link.
PSU Antec HCG M Series HCG-620M 620W for $40

MSI R9 270X for same price $140, but it is better than the gtx 750ti.

If you want NVidia GPU, I recommend to get the gtx760, even gtx660ti. And the HCG-620M will handle those GPUs.
