Hello guys,

I recently went out and replaced my i3 4130 and gtx 750 with i7 4790 and gtx 960 4gb. However in the process of replacing the processor, I messed up and the mobo cpu socket pins got damaged and so the computer wouldnt boot up.

So I need a quick replacement of my mobo. I dont have much cash left so I will stick with the cheapest option available.
Earlier I had ASUS B85M G
But I am looking to replace it with Gigabyte GA-H81M GAMING 3 mobo.

Can you guys please tell me how will this mobo fare? On paper it seems real nice-- it has a pcie3 slot for gpu, 16gb memory support and 2 usb 3.0 and 2 sata 6.0 gbps.

So what do you guys say?

Hey, thanks for the help. Just two questions-

1) Can you please confirm whether it supports 64 bit or not?

2) Can you please confirm whether it supports pcie3.0 or not?

The official website is confusing me. Anyways, once again, thanks for the help.

the both are pcie 2.0 and not 3.0 and they both are 64 bit.

the 2.0 pcie slot won't make any difference for the 960 so it's not worth worrying about. even a high end card won't fully use that slot. it is equivalent to a x8 3.0 slot which is more than enough for any card.

Same chip architecture, so still 64 bit (not really sure how that came up?) I believe all LGA1150 boards support 2x8GB memory configurations. Larger boards with four slots generally support 32GB. (4x8GB)

Haswell chips support PCIe 3.0, not all motherboards offer all lanes though, B class boards sometimes only have 8x PCIe 3.0 lanes available. (PCIe 2.0 @ x16 equivalent, should be almost no performance difference)

so will there be a performance gap in 2.0 and 3.0?

so this mobo will be fine for me, right?

PCIe 1.1 @ 16x = PCIe 2.0 @ 8x = PCIe 3.0 @ 4x roughly.
PCIe 2.0 @ 16x = PCIe 3.0 @ 8x

Standard SLI or Crossfire config will have two top end cards at PCIe 3.0 8x If I recall correctly even cards like the GTX980 suffer only a 1% performance loss going from x16 to 8x.

All that increases with generation is bandwidth (Though I think there is a slight pipelining difference in 3.0, but that actually slows it down)

what do you mean by perform? it will run all the parts and boot up everytime you push the power button. you are not overclocking or anything else special, so it needs to do nothing special other than allow the system to run.

it'll be fine for what you want to do with it and won't hold anything back if that is what you are asking.

Thanks for the help. I was able to shell out more and got the MSI B85M E45 motherboard. I hope it will be good.

Your suggestions are welcome.

Thanks.
