z77 board with PCIE 3.0 x16/x16

Are there any boards out there currently that have dual pcie 3.0 x16 slots for sli configurations? I plan on going multiple monitors here in the very near future and after seeing some benchmarks, I imagine the higher resolutions can really utilize the extra bandwidth of dual pcie 3.0 x16/x16, any help would be appreciated, thanks!

It's not a matter of the resolution, it's the fact that there isn't enough data to shuttle over the bus to realize a gain going from 8x to 16x. Up to now the difference between 8x to 16x in PCI-E 2.0 has been minimal to negligible, a 8x PCI-E 3.0 is more than enough for any modern GPU. That said, if you are carrying over multiple 2.0 devices it may make a difference.

If you really want the bandwidth it may be worth it to go X79. Although the add in chips are able to multiplex the 16 lanes into more it has a negative affect on latency.

The difference between 16x or 8x is irrelevent in 99% of cases, Unless you purely do bench runs
The difference between 2.0 and 3.0 is 2x the bandwidth. It is still on copper, still uses the same connection, still has the same number of traces, it is just clocked higher with a more efficient encoding algorithm. There is no improvement in latency, or anything else for that matter. The only time it would matter is during compute tasks.

That battle royale is the main reason i made this post, the differences were

Hey guys thought I would post some interesting test results that someone over at /r/gamingpc did.

Running battlefield with gtx 680 in sli PCIE 2.0 x16x16 vs PCIE 3.0 x16x16.

258

I think the biggest shock here is the difference at the minimum frame rate in a triple monitor set-up. A 20 frame difference (32 vs 53 on ultra, 40 vs 61 on high) seems to suggest having the increased bandwidth is doing wonders in this particular setup.

I wish the graph was laid out a little better but still informative non the less.'

*edit*

Just a note that the asus P8z77 WS will do PCIE 3.0 x16x16.

True but results speak for themselves..... there's considerable performance gains to be had with 3.0

These boards will do it:
G1.Sniper 3
EVGA Z77 FTW
ASRock Z77 Extreme9
ASUS P8Z77 WS Revolution

Also Maximus 5 Extreme and some other boards to be released in the near future but which have not been announced will support this feature. Maximus 5 Extreme hasn't been announced and thus is not included int he list.

I like the Sniper 3.

Agreed. I like the Sniper 3 or the EVGA FTW. I have a few months to decide.

Where's the legend? W/o it this graph makes pretty much no sense =\
