Will any 1155 boards support 2 x 16 mode for Crossfire/SLI

Wondering if I should wait for Sandy Bridge if I want to run Crossfire/SLI, or should I get a current 1366 board? I don't want to run 2 x 8 speed.

Also, when is 1366 being replaced like the 1156 is now?

Thanks

Late summer is the expected release of 1366's successor. Whether you go 1155/1156 or 1366 will depend on your usage. The 1366 Sabertooth is a great board w/ twin x 16 lanes, only $200 and an excellent overlcocker.

As far as I know, there is no real decrease in SLI/Crossfire performance at x8/x8 compared to x16/x16.

On one monitor at 1920x1200 or lower resolution there's nearly nothing noticeable. At 2560x1600 there's a small benchmark noticed difference. Unless you're doing three monitor 1920 or 2560 resolution gaming using the highest end cards, you're almost certainly not going to notice a difference.

I just want to be a little future proof, and I can see it making more of a difference in the future with newer cards etc.

I believe (correct me if i'm wrong) the Gigabyte UD7 is x16/x16

Yeah, I think there's several 1366 boards with x16/x16, but I'm wondering if any Sandy Bridge boards will also support x16/x16

I think he means the GA-P67-UD7, which does have it.

I may be wrong, but from what I understand the 1155 socket will be able to support 16 lanes, but for some odd reason it will not be able to support true dual x16/x16 video setups, in dual video it will most likely be x8/x8.

Now with the new Socket 2011 platform we should see the first full support of PCI Express 3 with 32 lanes, and also we may see quad channel memory.

It may not be a limitation of the technology, but rather a limitation of the physical grid array and number of copper traces needed to complete the task.

The GA-P67A-UD7 and the ASUS Maximus IV Extreme will both have dual x16x16, based off their websites.

Wrong my babies. The Asus Maximinus Extortion IV will only run x16 with one or three cards. Dual cards will make it run x8/x8 while triple will force it into a x16/x16/x8 mode.

Why they did this, nobody has the slightest idea.

I think the ASUS P8P67 Revolution can do x16/x16

The Gigabyte GA-P67-UD7 officially does 16x/16 in dual and 16x/16x/8x in Tri-Card.

ASUS P8P67 Revolution can't

this mobo was never revised after the issue with the northbridge about the 6.0 Gb/s ports; rev 1.0 is the only one available.
