Great build, but it's not what you want.
That build is really well balanced but it's not going to last you 4 years, I whipped this up

There's a combo deal on that mobo, so it comes out at the same as that extreme 4.
The ram is some cheap CL9 kingston ram, nothing special it's good.
I dropped the SSD, as much as it sucks doing so the extra $120 was better spent on other components, and SSDs will see a drop in price within the next 4 years, so it's well worth it to wait.
That 7950 is not voltage locked and has a great cooler, overclocks like a beast, same as that mobo (should be able to take that 8350 pretty far).
The TPC 812 is on sale for $40! STEAL.
I know people hate windows 8, but if you're building brand new it has some tangible performance benifits over windows 7. (honestly i'd just "acquire" a copy)
Got you some entry level peripherals from cooler master, tested them personally and they're pretty much the shit. (buy a steelseries mouse pad).
Swapped the case, but if you had your heart set on a z11, then use the z11. Doesn't really matter.
Pretty much the most bang i could muster. If you could drop the OS, then a 7970/SSD become tangible once more.
