Problem with getting the 3820 is you will likely have to pay more for a motherboard than you would for an i7 3770. LGA 2011 mobos are expensive. If you actually use applications that will benefit from quad channel memory, or plan on doing a triple or quad SLI/Crossfire setup, it might be worth buying into the LGA 2011 platform. If not, I'd just get the 3770 unless overclocking is a big deal for you. Even without overclocking, the 3770 is still a very powerful CPU that will likely last you for years.
