To start with, if I was building a serious gaming system (which, as I said, I'm not), I'd overbuild it. LGA2011 motherboards are around $200-250, and nobody's builiding serious game machines wth $70 AsRock boards anyhow. An X79 board wouldn't cost any more than all the Asus Maximus boards that people use all the time. And the SB-E I7 is cheaper than a comparable 1155 i7. Not sure what all the handwringing here is about over using an LGA2011 i7-3820. It's a bargain if you don't care about an iGPU, which you wouldn't in a gaming machine.
Where in the world do you think you're going to save $500 using LGA 1155 rather than LGA 2011? I can buy an Asus P9X79 and an i7-3820 together for $480 at Micro Center. The rest of the system is basically the same, so you'd have to get your cpu and mobo for free to save even close to $500. An Asus P8Z77-V PRO and an LGA1155 i7 would cost just as much or more. I wouldn't build a serious gaming system around one of your famous $25 motherboards. Face it. All the real money is in the graphics cards which you have to buy either way.
"Serious gaming" is a meaningless term. What precise circumstances would you say LGA 2011, with a significantly more expensive mobo/chip setup would actually produce better results?
At 2560x1600 or below, there's no point in anything more than an i5. Hell, I'm still waiting on Whiteboy to produce numbers showing that an i7 makes any difference in high-resolution (ie multimonitor/SLI) gaming setups. Even if you want an i7 those are available for 1155. So CPU isn't a reason to do 2011.
So next? Doing SLI at x16/x16 vs x8/x8.
If you can find articles from reputable sites that show significant differences in performance between the two, I'd love to find them, because all I see is that x8 vs x16 makes no perceptible difference in performance.
So what's left? Tri-SLI, I guess. But considering you can crush most games with SLI'ed 670s, even at 5760x1080, it makes very little sense to go with tri-SLI.
So as far as I can tell, serious gaming means: I want to run a tri-sli setup for a 3-monitor 1080p+ setup because I must have 60+ fps on current games with detail settings maxxed out.
EDIT: And I just found there are at least two Z77 boards that will do full 2 x16 and even 4 x8. So yeah, that pretty much invalidates any reason to go LGA2011.
