I was debating on whether or not to build a new system other than the dual socket one I listed here.
I was researching the new 3770K Ivy Bridge chip as my main rig processor but the more I looked at reviews of the chip over all the less I was impressed. These chips have a MAJOR design flaw, as Intel has decided to go with a cheaper variant of heat paste between the CPU die and the internal heat spreader (internal you cant see it), the standard in Intels' own chips, as well as competitors has been a flux-less solder for better heat dissipation the result is a hotter running cpu at factory speeds and even hotter with overclocking and over volting with even superior cooling. There have been people reaching 100C!, this temperature for a cpu is very lethal, and will fry it for sure. One video on youtube shows idle temps@ factory speeds, with a closed loop liquid cooler, 80-90c per core, this is insane.
This is only one of many articles regarding this issue, Google Ivy bridge TIM and you will see lots of reviews of this same issue
I just wanted to give everyone a heads up in case you were debating on going this route, stick to the sandy bridge or an amd equivalent both use the old process material, and while the performance specs of the ivy bridge are really good for a cpu, eclipsing their own sandy bridge as well as amds' current offering I do not fully believe the added performance is worth the risk of a catastrophic failure and associated down time.
Have a nice day, see you on the battlefield!
