[Build Ready] Building a ~$1500 3D modeling and gaming computer, could you guys look this over please?

First of all, a huge thanks to everyone on BaPC! I’ve been lurking and researching for a while and I think I’ve finally come up with a build. My budget is ~$1500, but I'm willing to go over if need be. This computer will be used for lots of 3d modeling, a bit of photo editing, and of course plenty of gaming (Skyrim, BF3, Saint’s Row, etc.).

I plan on overclocking for sure and maybe crossfiring at some point in the future.

One question that I had was whether I should go with the ASRock Extreme 4 or the Asus P8Z68-V Pro. I decided to go with the ASRock because it was cheaper and has the same or better specs for the most part.

Side note: These are only the parts I plan to buy, I’m going to wait for the prices on most of them to drop before I buy them. Also I already have the keyboard; I got it on sale for $40, and I left out the monitor because I’m going to buy whatever I can find on sale in the next week or so.

Let me know what you guys think! Thanks!
