Did you get all your components already? There is a good deal on the MSI Z77 motherboard on Newegg for $65 after rebates(check out kduvernay thread on z77 mobos). If you have a micro center near you, they are selling the 3570k for $189+tax and if you really want to stay with gigabyte mobo you can bundle with CPU for 49.99+tax.
For ram GSkill ripjaws are on sale for $35 for 8 gigs on newegg.
Last I checked Kingston hyperx 120gb ssd was on sale @ staples for $75. If you can score a 25 off 75 coupon you could get it for around $60. Also read the hyperx performs better than ssdnow.
Corsair cx430 can be had for $25-35 after rebate as they go back and forth between $10 and $20 rebates.
My current build with CPU, mobo, memory, ssd, case, PSU comes to $435 not including cost of OS, trackpad, wifi, video card, Bluetooth. With i3-3225, it comes to a whopping $370 (the new PovoMac?). If you don't game HD4000 should be ok and you can always add video card later if needed when a better price comes along.
