Best P67 or Z68 motherboard?

get a Z68

get what ever has the features you need
from a good manufacturer

the good one is asus p8z68 vpro or asrock z68 extreme4 but asus is better for wide spacing sli/crossfire and many good features...

I wanted the fatal1ty extreme. Costs a lot, but amazing features and looks stunning.

Well MSI's Z68A-GD65-G3 is one of the best options out there. And its price is not very high. It also supports pci express 3 that is not vital today but a future feature is always welcome  .

You want a Z68 for sure if you plan on using it for things like video editing, etc.. due to the IGP. If this is a gaming build, than either Z68 or P67 will do just fine.

Yes, it's supposed to be a gaming computer   - I've put a $700 budget for it. That's why I'm tight on budget. Motherboard, I think, should not exceed $150 as I'll, hopefully, get HD 6850 (if I get a 1080p monitor).

So, will have a dedicated GPU. So will not use the Quick Sync. And I'm not planning on getting an SSD these days, so SSD Caching won't be of much use. It's just, I heard that P67 had some issues with SATA.

i'd try to get in at least a 6870, if you can

Can't atm; budget. I know that 6870 is not only slightly more expensive than the 6850, but budget is too tight lol.

About Gigabyte's P67 for example, there's UD3, UD4, etc. Up to UD7... Which is the best? and what is the difference between them?

Same with Z68 I think.

ASRock? Are you kidding? If you want solid performance on a tight budget, go for Gigabyte. Some of the best Z68 is from Gigabyte are about $100 to $120. If you can squeeze a little more, go for ASUS.

well, ud7 is better it has 2 pci-e x16 x16 at full speed but it's not neccessary to use x16 x16, using of x8 x8 is almost perfect idea.they all are good boards.

there is not much difference between x16/x16 and x8/x8
that Asrock board is ok .. @ Why_me welcome back comrad  
At that price level they are all pretty identical .. also would you mind listing your other components?

that's what i told x8 x8 is almost a perfect idea and many of people are using x8 x8. 

look for microcenter close by
