For gaming the lga1155 platform is recommended.

For gaming the lga1155 platform is recommended.

Why?

Not to cast doubt on your expertise but why?
1155 support only 1 full speed PCI 3.
2011 upto 4
1255 support dual ram
2011 support quadro

ONLY problem for 2011 is fact that only SB CPU available atm. IB-E planned for Q3 2013. Sandy Bridge CPU do not officially support PCI 3 and USB BUT... unofficially NVIDEA has a fix for it.

It does not work for all configuration and hence request for help. Is anyone run video in full PCI 3 on 2011? Can u recomend mobo/v-card?

PCIe is important for gaming but here you can see the scaling difference between X8 and X16 so just based on costs LGA1155 makes more sense than spending the extra money on LGA 2011 for that last 1% of performance squeezed out at X16 http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI-Express_Scaling/23.html

Very strange.
According this chat there is no difference between PCI 3x16 and PCI 2x16

That is because they do not make any cards yet that can max out the 2.0 interface!

 

[Earlgrey]

Even so they advertise card as 3.0?
Well then I waste my money on 680gtx for $500

Still a very powerful card and it is not PCIe 3.0 that makes it powerful
