Gennaios :
despites the 3820s socket which will give you the opportunity for upgrading the 3770k is way more powerful than the 3820 thats for sure!
Not way, theyre actually quite alike. 3820 preforms like other i7 sandys (bit better)but if anything I would go for 3820 beacuse you can upgrade to 3970X later (or 30k). But keep in mind that 2011 mobos are more expensive
