Microcenter will give you $50-60 off a Z68 or P67 Motherboard with the purchase of your 2500k.
I bought my Gigabyte GA-Z68XP-UD3 for 109.99 when I bought my 2500k there. Much better motherboard than the ASRock Extreme 3 Gen 3. Mine booted first try and had all the options I wanted to OC mine very easily. Mine is running perfectly stable.
Oh really? How does it work? Do I just add a motherboard to the cart with the i5?
