Currently i am NOT very happy with the Gigabyte x58 boards... to much vdroop... also the PCI Express Layout make my vcard scream for more space between each other... The one located at the top is having 85C degrees under load and the bottom one only 70-75C degrees under load...

I am considering to keep my 920 and buy another mobo... i am looking at the eVGA x58... but i think to use both PCI Express in x16 you have to use the 1st and 2nd PCI Express slots... i am right?
Yes, but the EVGA is out of the question cause it doesn't support sleep mode.
I saw this as a problem 2 months ago when I realized if the middle slot is used for secondary PCIe card when doing SLI, it would choke the air supply and at best, cause the fan to run full blast with the irritating noise that results. My own testing bares this out. As far as I'm concerned, the middle slot cannot be used cause of the increase in noise, so the bottom slot must be used if doing SLI. The only question is what is the ramification of using the bottom PCIe slot? Some mobos offset the bottom slot towards the bottom so that the vid card will interfere with the case (gigabyte, MSI I believe). The DFI and EVGA position the bottom slot more favorably so that the card may not hit the case. The EVGA is out cause it doesn't support sleep mode, so that is a non-starter. In benchmark tests, I found there to be virtually no difference in graphics performance using a 16x/16x config vs 16x/8x, like maybe 1.5 - 0 % depending on the benchmark. I like the giga so I modified my case by cutting out the area of the case that would cause the interference problem, so I'm now running SLI with the giga ud5 using the top and bottom slots and seeing no performance loss to speak of with the 16x8x config. The DFI x58 board has the advantage of favorable slot placement and 16x/16x config. I had this board for a few weeks, returned it cause there was static on the sound card.
