Why are you buying a motherboard+CPU combo AND a second processor?
Don't bother with the i7 unless you're doing HEAVY video / audio editing. The i5 in the combo is actually better, if you're gaming. (Keep the combo, and don't forget the promo code for $20 off on the motherboard)
Your graphics card link is dead - what were you thinking of? General rule of thumb is to spend twice on the graphics card what you do on the CPU.
Ram: HAHAHA. With Battlefield 3, Photoshop AND 20 tabs open in Chrome, I use just over 6GB system ram. Save yourself the cost and get 8.
You didn't go overboard on the PSU! I'm impressed. That's a good one.
That's a slow hard drive - get one that's 7200 RPM or greater. I would STRONGLY suggest just one terabyte of hard drive (which is very hard to fill) and a SSD for your OS and programs.
