Finalizing build... Any recommendations?

[fmdunlap]

Hey everyone, so I'm looking to finalize a computer build since I've saved up some money and want to get your opinion on it. I've already decided to go with a 2600k, seeing as it's the most powerful of the Sandy Bridge chip sets and I can overclock it. I'm also thinking about putting two EVGA GTX 570s in SLI. Anyways, here's what I've got so far:

CPU:
Intel 2600k
(http://www.newegg.com/Product/Product.aspx?Item=N82E16819115070)

Mobo:
One of the two:
ASUS SABERTOOTH P67 (REV 3.0)
( http://www.newegg.com/Product/Product.aspx?Item=N82E16813131702 )

ASUS MAXIMUS IV EXTREME (REV 3.0)
( http://www.newegg.com/Product/Product.aspx?Item=N82E16813131700&cm_re=Maximus_IV_extreme-_-13-131-700-_-Product )

GPU:
EVGA SuperClocked GTX 570
( http://www.newegg.com/Product/Product.aspx?Item=N82E16814130595 )

PSU:
OCZ ZX Series OCZ-ZX1000W
( http://www.newegg.com/Product/Product.aspx?Item=N82E16817341045)

Memory:
G.Skill 8GB (4x2GB) DDR3 1600
( http://www.newegg.com/Product/Product.aspx?Item=N82E16820231325 )



Approximate Purchase Date: (Soon... Within the week)


Budget Range: $1800-$2200


System Usage from Most to Least Important: Gaming, more power intensive tasks


Parts Not Required: Peripherals & HDD


Preferred Website(s) for Parts: Newegg.com


Overclocking: Yes


SLI or Crossfire: Yes

Monitor Resolution: 1920x1200

HDD's I've got covered, as well as cooling (in my case a Corsair H70) and for a case, I really like the NZXT Phantom (I really like the newegg exclusive black and orange color scheme) but I am open to suggestions.

Anyways, tell me what you think! Haven't spent any money on it yet and would love to get a few gold nuggets of advice.

Thanks in advance!!

(P.S. not my first build... It's just been awhile)

(P.P.S. I've got a max budge of ~$2,000 I can give or take about $100 or so. I've already got some of the hardware so don't worry about exact cost.)
(P.P.S. I've
