Hello, Noob here! Yes I have OCed B4 but Im new to the forums. I saw this topic and could not resist. I am also torn between the 3820 and the 3770 at this point. This isn't helped by all the conflicting information. Here is a summery from what I have gathered so far...
3870
+Built for media editing, encoding ect...
+Suports quad channel memory
+Locked but can still OC to around 4.5 on air.
-Runs at 130w
-x79 is more $$$ (Can get some good deals on boards and RAM now!!!)
?Intel says "Yes" and "No" to PCIe 3.0 (it has 40 PCIe lanes)
?Runs ??? faster then 2600K (clames of 15% to 50%)
?Runs hotter/colder then 2600k
3770k
+Built for regular PC use, gaming, ect...
+22nm with trigate
+Runs at 77w
+Runs 5% to 20% faster then 2600k
+Unlocked
+7ghz liquid cooled (cannot seem to find any air cooled OC)
+PCIe 3.0
+z77 boards are cheap (Im going to bet z77 boards will cost the same as x79 boards with the same features. Not counting p67, I dont trust "Buy Now BIO Update Later" boards, usualy too many issues.)
-Reports claim runs cooler then 2600k idel, but hotter under load!
Most important question is...
*How hot it runs compaired to the 2600K/3770K
*Can it REALY support PCIe 3.0
* How fast is it realy compaired to the 2600K/3770K
I have seen indipendent testers say the 3820 is way faster in media editing, and about the same in everything else compaired to the 2600k. Then benchmarkers say the 3770k is only 5-20% faster then the 2600k, but every "Official/Unofficial" benchmarks show the 3770k dominating the 3820? WTH? Along with intel's yes/no on PCIe 3.0, I smell something, and it aint pretty?
