martinduque86 :
thanks alot flong!
EDIT: btw do you think 850w is too much for this rig? should i downgrade a bit? thanks in advance!
RAM:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231460
1866MHZ RAM; 8GB for $80. G.skill is also better than corsair in ram making, and the sniper series is really good.
PSU:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371050&Tpk=hcg%20900
$110 AR; it got 9.5/10 from jonnyguru, its 900w. The corsair HX 850 got 9.6/10, but is $155AR at the moment..it was never at $120 (you can check product price history for newegg/amazon here https://chrome.google.com/webstore/detail/ghnomdcacenbmilgjigehppbamfndblo#
(The cheapest the HX 850w was was $135 2 weeks ago).. the HCG is 0.1/10 marks worse than the HX850 from jonnyguru hcg900w, but the 900watter it is rated 50w vs 850 and $45~ cheaper. (Note theTR2 series is CRAP CRAP CRAP CRAP!!!!)
Motherboard : Z68/Sabertooth etc are good, but $200+ mobos for a $1200 system isn't good; spending that money on a better GPU etc will impact performance at lot more than minor ocing...
CPU: i5 2500k is really good, esp if you are overclocking.
HDD:
http://www.newegg.com/Product/Product.aspx?Item=N82E16822152185&Tpk=samsung%20spinpoint%20f3 This HDD is 1TB, and is faster and $25 cheaper than the WD black. The samsung f3 in the link i have shown is the most recommended product for any system by forummers @ tomshardware here... Its basically the only product we recommend for almost any system..
Graphics: The $255 6950 you have listed is good BUT...consider the GTX 570.
The cheapest GTX 570 is only $290AR, and is around 10-15 % better...
http://www.anandtech.com/bench/Product/293?vs=306 <69502gb vs GTX 570
The 570 doesn't win the first 5 benchmarks, but after that it dominates i.e. 91 fps vs 65.
I'd personally choose the GTX 570.... it is around 15% more cost, but it gives about 12% more performance, and that is a really good return at the $200 plus mark; i.e. a GTX 460 768mb can be found for $110, but it gives around 75-80% of the performance of an HD 6950 @ $250..and even wins in a few games...So getting the same % return per % money put in is really good above $200... People spend 40-50% more on a 580 and get 10%~ more performance.

http://www.anandtech.com/bench/Product/305?vs=306 GTX 570 vs GTX 580 ($290vs $475~)
I'd say a GTX 570 is great compared to a 6950... and really recommend it.
Heres a non-oc'd version ($290)::
http://www.newegg.com/Product/Product.aspx?Item=N82E16814162075&cm_re=gtx_570-_-14-162-075-_-Product by gigabyte
Heres an super OC'd EVGA version for $315:
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=gtx+570&x=0&y=0 (797mhz OC vs 732 normal speed). Either is a great buy.. but better maybe to buy the gigabyte version and oc it yourself; saving $25, unless you really like EVGA and their lifetime warranty for gpu's etc.
Get the HCG900 watter if you want 2 x 6950's / gtx 570's / gtx 580's in SLI. The first 2 will easily be powered by it, even with high overclocking.
Get
http://www.newegg.com/Product/Product.aspx?Item=N82E16817207007&cm_re=xfx_650w-_-17-207-007-_-Product for $69 (haha) xfx650w, if you want ANY single GPU (even hd 6990/gtx 590). It will easily run an overclocked 570/580, with an oc'd i52500k.
Motherboard: If you "REALLY" want z68 (no idea why you would..)
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128494&cm_re=gigabyte_ud4-_-13-128-494-_-Product $180
The ud3 is $130
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128476&cm_re=ud3-_-13-128-476-_-Product
and ud3z68 version is $144

Sabertooth is better than these mobo's, but at $210 far too expensive; invest the savings of $30-80 in getting the gtx 570. Definitely get my memory recommendation; $40 saved for better RAM. The hcg900 will perform miles better and save another $15. The HDD will be faster and save $25.
That's a saving of $80 on better parts compared to your current build, and a further $30-80 on a motherboard downgrade.
The only thing i recommend you actually pay more for is the GPU; $35 more, or $60 more (60 for EVGA). That means you'll potentially save $125 on my recommendations, with a better gpu, better ram, better psu and better hdd, and worse mobo. That means you can actually buy an SSD for your boot drive (further speed up)... If you start saving in key areas, you can get a more powerful system, and a faster system
. The GPU is always the most important; the only balanced system is the one where most of the money goes to a good gpu!
