thanks I found out that p55 and p67 only support 2 gpu's at x8/x8. I have to go with the x58 chipset

In reply to: my source

and here's what the Gigabyte product manuals say about the Gigabyte GA-PA55A-UD7 and also the GA-PA67A-UD7 respectively. Perhaps Gigabyte is wrong but it sure looks like these products both say they offer 2 PCIe X16 running at X16. Do you read the Gigabyte info same ?

http://download.gigabyte.us/FileList/Manual/mb_manual_ga-p55a-ud7_e.pdf

"Expansion Slots ? 2 x PCI Express x16 slot, running at x16 (PCIEX16_1, PCIEX16_2) (Note 2)
? 2 x PCI Express x16 slot, running at x8 (PCIEX8_1, PCIEX8_2) (Note 3)
? 1 x PCI Express x1 slot (The PCIEX16_1, PCIEX16_2, PCIEX8_1, PCIEX8_2, and PCIEX1 slots con- form to PCI Express 2.0 standard.)
? 2 x PCI slots"

Note 2 says
"(Note 2) For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16_1 slot; if you are installing two PCI Express graphics cards, it is recommended that you install them in the PCIEX16_1 and PCIEX16_2 slots.

The GA-P67A-UD7 shows same...

http://download.gigabyte.us/FileList/Manual/mb_manual_ga-p67a-ud7_e.pdf

"Expansion Slots
2 x PCI Express x16 slots, running at x16 (PCIEX16_1, PCIEX16_2)??
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16_1 slot; if you are installing two PCI Express graphics cards, it is recommended that you install them in the PCIEX16_1 and PCIEX16_2 slots."

Given the information and the prices....I'd be looking at all the MBs with dual PCIe X16 slots running at X16 if that was a required capability. The GA-PA55A-UD7 and PA67A-UD7 are very pricey versions of the socket 1156 and 1366- based MBs.

I just looked at Newegg.com and they are now showing over 30 MBs based on Intel socket 1155. Last night there were none.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
