I would take this Newegg.com - Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I53570K over the Core i7-3770 you have listed....unless you just really want an i7. The 3570K is rated as one of the best valued CPU's out there, and will run every game you can think of without breaking a sweat. It is also $80 cheaper! Also, you may want to upgrade your motherboard choice to something newer, such as the Z77 chipset...... here Newegg.com - Computer Hardware, Motherboards, Intel Motherboards, LGA 1155, Intel Z75/Z77, Intel Z77.
I know without a doubt you will be happy with the new components you are looking at. Not only are you getting amazing bang-for-the-buck deals, you are getting the newest technology that will last you for quite awhile. Buy once, cry once.
