I'm in 2011 for 16x16x SLI, quad memory and overclocking for $100 than 1155. A 3820 is less 'locked' than previous OCing w/LGA 775. It's 'locking' doesn't result in *any* limitation. There had been little issue w/getting 4.6 Ghz and many folks are getting 4.8-5.0 Ghz. Same as 1155 SB. You can mosey over to the 3820 OCing thread and see.
A few years back like... 2007-2008, faster duals reigned supreme and folks said quads weren't worth the money. A lot of folks. I'm of the notion, in 3-5 years, a 6-8 core processor at a fair OC of 4.5-5.0 may hold fine w/a 5.5-6 Ghz quad with archetectural improvements. While they're still serviceable, a 4.0 ghz c2d isn't as good as a c2q. I wouldn't have help only LGA 775 nearly as long if I'd stuck w/a E6600 instead of selling it and paying an extra ~$100 to go to a Q6600. I won't take the nay-sayers of 2011 over what I've seen happen in the duals vs quads battle. So long as the support continues... more cores and perhaps HT will be the path to take.
I think the quad memory is a bust for gaming but the 40 PCI-E lanes and being able to sell the 3820 for ~200-250 and going w/a 6/8 IB for 500-600 will give it enough life to go a few years beyond what SB/IB on 1155 is capable of.
This is all gambling that programs take advantage of multi-threading and HT is worth a damn years from now. Maybe... maybe not. I think it was worth the $100 gamble. Plus, any revisions that come out w/IB on 1155 should (hopefully) be incorporated w/IB-E... with maybe an improvement along the way. There won't be any IGP that I don't care about taking up room either.
I'd bet the majority of everyone, at least on OCN, w/a 1155 SB/IB setup will have moved on in 2015. I'd like to have the 2011 for 5 years. OCing to me isn't about bragging rights. It's about taking something that isn't hacking it anymore and extending it's life to make it comparable to stock clocked new tech. It was time to move away from a Q6600 when it 1) couldn't play some games w/o limiting minimum frames and 2) At it's max OCs couldn't hang w/a stock clocked 2500k, given it's improvements.
I got an asrock extreme6/GB. Has a sound card that'll hopefully work as well but have better driver support than my PCI Xtremegamer X-Fi card. For around $250, you can get it w/o the sound card. There was a good review of all socket 2011 mobos I googled. I used the reviews, knowing I'd probably never do more than 2 cards in SLI along w/looking at pricing as my deciding factor. The comparable 1155 mobo I looked at was about $100 less. The 3820 was about 30 under a 2600k, and clocks similarly. I had to get DDR3 (was in the dark ages w/DDR2) so that was a little under $100 for 16 gb of fast ram... twice as much as I'll ever need in 5 years.
