[Solved] New build for BF3/Rage/Skyrim. Help, criticism, critique welcome

Hello there. Im building a new rig specifically for the games above, as well as future titles, and I'd like some feedback. Id like to play these game at high/ultra settings if able within my budget. This is NOT my first build, I had been doing it for years up until about a few years ago due to money, travel, moving etc, and im pretty out of the loop, but any feed back would be appreciated. If you think there are components I can find alternatives to to shave off a few bucks cool, as long as it doesnt sacrifice power. Thanks much.

For: Gaming (battlefield 3, skyrim, rage, etc)

Budget:1000-1300 USD

Parts: Microcenter (all prices are from their website in the last week or two, Ill be picking them up in store)

Parts not needed: monitor, speakers, mouse, keyboard.

Components list:

Case: Nzxt Phantom II - 112.00
Cpu: I5-2500k - 180
Mobo: Gigabyte GA-Z68XP-UD3 LGA 1155 Z68 ATX 155.00
Psu: Corsair Gaming Series 800 Watt High Performance ATX 140.00
HD: Seagate Barracuda 7200.12 500GB 7,200RPM SATA 6.0Gb/s 3.5" 45.00
Optical: not concerned. approximately 20.00
Ram: Patriot Viper Xtreme Series 4GB DDR3-1600 or Patriot Viper II Sector 5 Series Patriot Viper II DDR3-1600 each 50.00

GPU: either 2x GTX 460's 1gb or x2 Ati 6850 1gb. Id prefer 460's however im finding them increasingly difficult to find on the market.
$320.00-340.00

Do you think this is suitable for high settings on the games mentioned, and holdup for some time?
My other alternative would be a single GTX 570 and at a later date, buy a second one. As is theyre roughly 300.00-320.00

Is the dual card set-up better or the single 570. Im looking for instant gratification here. If the single 570 pulls as much weight as X2 460's or 6850'S ill take it.
Otherwise dual cards are what id go for.

Total around 1050.00 w/o cooling, tax and MIR

The other component that im most unsure of, is the heatsink/cpu cooling, I was looking at the Noctua Dh-14,
but it isnt available at microcenter, and i was actually hoping for something more around 50-70 to wrap up the build that i old find in store that is community approved and recommended.

Thoughts?

Also already have OS. Sorry missed that

Yes im definitely willing to snag parts from NE, I most likely still get the mobo in store to get started, I have other components from other pc's that can sit in till the new stuff arrives.

Thanks much for the feedback!

The case is a bit smaller than Id like, but i am considering a sata drive. I might just over extend my budget a bit and get one.

Edit:
Awsome thanks for the links

cases are subjective. I like Rosewill cases as great deals for the money

I'd go with the 570 and SLI another when they're cheaper.

I'm a bit out of the loop on nvidia cards at the moment, however. I only suggest this because a year ago I went with 1x 6970 instead of 2x 6850s and it will not stutter! It's so great I got an open-box model for $300 and it works great, so I got lucky and saved ~$60. IIRC the 2x 6850s would slightly outperform 1x 6970, but gaming at 1920x1080 doesn't have any problems whatsoever. Also have no idea how my single 6970 will handle Skyrim and BF3. Sadly, my gaming rig is out of commission during the BF3 beta.

Also, I think with the 1155 as opposed to the 1366/2011, it would make more sense to stick with 1 very powerful card and then start filling up those lanes with a second card later, instead of using up it's potential for 2x SLI immediately on cheaper cards.

i use that motherboard, it serves my purposes well and overclocks like a champ for gaming, incredibly intuitive uefi bios, my first overclock was using this board and i am at 4.5 GHz, there was a weird double-post, triple-post issue that a lot of reviewers mentioned, although it is related to the BCLK speed which setting it to 103 as opposed to 100 seems to cause and if you set it back to 100 it fixes that issue (perhaps somewhat too in-depth although just something handy to know, if you opt for that board in the end). also i had a good experience with msi previously
