I built an Intel I7 4790k LGA 1150 about a year ago and I have been very pleased.
your best bet (to save a few bucks) to get exactly what you want is to build your own.
Its pretty easy actually.
You can buy a CPU + Motherboard bundle and then all you need is a Power supply, SSD hard drive, a Case and a copy of windows.
I shop here for all my builds:
http://www.microcenter.com/site/brands/intel-processor-bundles.aspx You can get a decent bundle CPU/MOBO for around 300.00+ bucks.
I wouldn't be too concerned about video unless your Mobo doesn't have onboard video.
I use onboard video that has Dual DVI for 2 monitors.
I salvaged my old case, my old Hard drive and Windows copy from my previous build which was an AMD FX.
I built this new Intel system for under 600.00 bucks.
I should also mention it depends on how many sample library's, plug ins, exc you plan on using.
My typical projects have 5 Synths, 20 Audio tracks and upwards of 50 plug ins.
Ive yet to see my system stutter or bog down.
