Trying ot make up my mind between these boards

Could someone tell me what (if anything) lose by going with this

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

instead of this

http://www.newegg.com/Product/Product.aspx?Item=N82E168...


Cost isn't my primary concern, system is being used for multimedia, gaming, hopefully some Overclocking. I chose the first board because it offered x16x16 for duel SLI but on checking out the second it seems to offer that also. am I mistaken? am I correct in thinking its a better buy because its a z68 that basically does everything the lower lvl board does?

Any thoughts or suggestions would be very welcome

thanks!

The first board doesn't support dual x16 speed.(Just like other P67 boards,it supports SLI/CF @ dual x8 speeds)
I'd recommend the second one because Z68 is newer and has more features and also ROG series usually tend to OC better

the only difference between z68 and p67 is z68 is better at encoding videos, and allows for ssd caching (which is pointless any way).

the Maximus has 8 USB 3.0 vs 2 USB 3.0 on the P8P67

The dual x16 vs dual x8 will not make a difference

the maximus is E-ATX meaning only certain cases will handle it (it is 1 slot longer than standard ATX)

if you plan on Overclocking the Maximus is better.

But overall, both boards are great boards, depends on your case and your budget, either board will do you just fine

IMO - On the Sandy Bridge P67 or Z68 and 2-WAY SLI there's no practical differences between x16/x16 and x8/x8 even on the GTX 570/580. Reason, the NF200 added latency vs native Intel spec {0~3 FPS} isn't a justification to get the more expensive MOBO's. If the plan is to go Sandy Bridge and 3-WAY then the NF200 is the only SLI option.

NF200 x16/x16 SLI MOBOs {same performance}:

From what I have read, 8x/8x for crossfire results in better FPS than 16x/16x - so basically you get more power for less money.
Much like 2500k/2600k vs 990X - if you see my point
