You might consider buying your Motherboard from Micro Center as well. Right now they are offering a $50 discount when you buy the I5 2500K and any Motherboard together. That's on top of their unbeatable price on the I5 2500K at $179.99. This will allow you to spend more money elsewhere.
If graphic design is your main concern I would actually upgrade to either the 2600 or 2600k if you want to overclock. More threads with this chip set over the 2500k. Programs like photo shop will take advantage of that.
i7 2600k $280
Asrock Z68 Pro3-m $110
Gigabyte GTX 560ti $210
GSkill Value series 8gb ram $37
LG 22x $18
Cooler Master 212 $30
Hitachi 500gb $70
Antec ECO 620w $60
Total: $900 Besides the Processor and MB, everything else is from Newegg. If you were to find a cheaper case, then you could change the GTX 560ti to a GTX 560ti 448 which is close in performance to the GTX 570.
