Need Motherboard to Support i7-3770K and Two PCIe2.0 Video Cards

Hi everyone,

I'm looking for a motherboard that can support the i7-3770K and two PCI-Express 2.0 video cards. With that in hand (along with some minor wants: 4x240-pin DIMM and at least 2x6Gb/s SATA), I found

But I'm not sure if this motherboard will take the two video cards in the PCI-Express 2.0 slots because it says "(1x, 4x)" next to it. Does anyone here know what that means? Will I be able to run the two video cards at their full speed?

If not, does anyone have a suggestion as to which motherboard would work for my requirements?

Thanks in advance!!

  1. U can definitely use this one -> ASRock Z77 Extreme 4 -> ... Latest Z77...

    I just build PC with this mobo and I like the BIOS, its looks like this.

    Works as expected @ 4.4GHz

    That is a great mobo choice for the CPU. It has good power design for OC.

  2. Your link is not good ...
  3. Cool.

    Why are u choosing the 3770K, instead of 3570K?
  4. Hey Nikorr,

    Thanks for your response! I figured it out.

    The board that I was considering (2nd attempt, ASRock H77 Pro4-M: would not have worked. I ended up calling EVGA about the video cards. So basically, the video cards need at least an x16 slot with PCI Express 2.0 x8 speed. So I needed to find a motherboard with 2 PCI Express 3.0/2.0 x16 slots that both can be at least x8 speed.

    So your ASRock Z77 Extreme4 would work, but I already decided on MSI Z77MA-G45 (, mainly because of lower cost.

    Thanks again for your input! Much appreciated. :)
  5. It's not much, but for the slightly more L3 Cache (6MB vs 8MB) and clock speed (3.4GHz/3.8GHz vs 3.5GHz/3.9GHz).

    As of today, it is a $110 difference. And to be honest, it's not that worth it. But for the next step up, it's the E3-1280V2, which is 0.1GHz more for $300ish more. Then it's the E3-1290V2, which is another 0.1GHz more for another $400ish more. So I guess I decided to stop after the $110 jump.
  6. OK,

    Do u edit videos and do other editing tasks or just playing the games?

    I think we can save u some money here.
  7. First, to get 3770K, is good for video editing and such.

    #2, for gaming its not better than 3570K.

    #3, Overclock is better. So get better mobo and overclock and enjoy it, if u do game only.
  8. If u never OC'd before, its easy with this CPU and u can get ~30% more power.
  9. Also, that MSI mobo choice is not good choice for 2 GPU card set up, as it is Micro ATX .
