Depending on how serious you are about graphic designs you might want to aim for 16GB of ram. Unless you're OCing the cpu you don't need an aftermarket cooler. Also unless you plan on going sli there is no need for a 100 dollar motherboard.
ASROCK has some nice boards for cheap. As long as it has a pci-e2 or 3 slot and enough slots for your ram you'll be good. Only time you got to worry about motherboard selection is when you get into OCing, crossfire, Sli.
If you have a micro center near you they have 40 dollars off z77 boards with the purchase of a i5-3750k which is only 169.99 there. So you could get way more cpu and mobo for a little less than you have selected now.
