I'm going to sound like a huge nube, but what ports do you need to fun SLI or crossfire?

Many board have a PCI E x16 and another PCI E that runs at x8. Is this standard? can you get boards with 2 PCI E at x16?


this board says when you use both slots then they will run at x8.

basically what i'm asking is... would SLI or crossfire on this board be ideal or should i look for a different board?

Your board is just fine, when you add a 2nd card for SLI they with run in x8 x8 mode, which you won't even notice the difference from x16.

What is your current graphics card?
 
How many displays and what display resolution will you be running at?

If you're running on a 30" or smaller display at a resolution of 2560x1600 or below, an x8/x8 SLI or CFX configuration will perform the same as a x16/x8 or x16/x16 configuration. The only time that you should even be slightly concerned about running at x8/x8 is when you move up to a multiple display setup at a resolution of 5760x1200 across three displays in NV Surround/CrossFire Eyefinity mode.

If you're not running at a resolution of 5760x1200 across three displays in NV Surround/CrossFire Eyefinity mode the x16/x8 configuration of the GIGABYTE GA-P67A-UD4-B3 will be absolutely fine.
