Looking for a PCIe 3.0 board....

Hello,

I am building a new computer and have decided to base this around a motherboard that is PCIe 3.0 compatable. I want to have at least 2 3.0 slots that can run at x16 together. Not 16x,0x or 8x and 8x like most that I have found.

Anyone know of a Mobo that would do this? I am leaning more towards the 1155 socket but would consider am3+ if it met the needs.

Other requirements:
32 gigs mb support or more

could you please tell us why do you need the mobo having 2 PCI-E 3.0, also there is 1% difference between x16/x16 vs x8/x8.
Getting the mobo with x16/x16 is just a totally waste.

If you really need to have two PCIe 3.0 x16 slots at full speed (I can't imagine why unless this is a compute machine, there isn't a single PCIe card that uses that much bandwidth and consumer graphics cards don't even need more than a PCIe 3.0 x4 slot, PCIe 2.x x8 slot, or PCIe 1.x x16 slot to deliver over 95% of their performance), then get an LGA 2011 board with an X79 CPU. The only actual use for two PCIe 3.0 x16 slots, that I can think of, would be to facilitate two high end Tesla cards for some serious compute power.

Is it really that insignificant of a diff between 8x and 16x? If thats the case, then I dont care. I was thinking it was a big difference. If so, then I have many choices. Thanks for the information.

Ther difference really is that insignificant. It's because most PCIe cards (including graphics cards) today simply don't use all of that bandwidth, so increasing the bandwidth doesn't make much of a difference.

Thanks guys. Any boards you recommend then with 2 PCIe slots? I am thinking with the H77 chipset, but not set in stone.

H77 shouldn't have two PCIe x16 slots, unless all but one of them are either x4 or x1 slots with the plastic shell of an x16 slot. If you want an Intel board with two slots, than Z77 would be your best choice.

you would need a z68 or a z77 chipset board that is labled crossfire/sli ready. some boards, although having multiple pci express slots dont have the ability to sli/crossfire
