(I am a computer parts and build consultant. If you would like to have a one on one consultation please feel free to contact me on my website): Here: www.IamApropos.com - This Build was completed October 4th 2012.
[Edit] as of 4/23/2013 My system has changed yet again - I no longer have SLI Gigabyte GTX 670OC cards, I have reverted to a single EVGA GTX 670 FTW Sig 2. - I will eventually upgrade to a second card and a 120Hz / 144Hz monitor. [/Edit]
(old build notes) This system is for heavy gaming - since gaming does not take advantage of hyper threading I chose the 3570k. Also went with 8GB of 1600 ram because a gaming machine will barely use 8GB which would make 16GB a waste. If I need to, the system will allow me to add more later. No need for optical drive since I download all the games + content off of steam or origin. I figured I'd throw this back up here with the addition I put into my system. SLI'd the GPU!!! Now I'll just start looking around for a great sale on a 120Hz monitor and use the 60Hz monitor for surfing the web / chatting with people while I stream live game play and live computer builds. The Extra storage I use my laptop to rip DVD's and store them and have it setup as a shared drive for my network so that anyone anywhere in the house can watch movies.
Most items I have in my system were purchased at a discount, with coupons, and combos. CPU:$200 MB: $145 GPU: $410 h100i: $99 Case: $99 SSD: $99 HDD: $65 PSU: $105 after rebate Win 8: $39 K90 KB: $89 *RAT 7 mouse: $75
