The PCIe on an Asus P8P67 going to be a problem?

post #1 of 11
Thread Starter 
My memory is a little fuzzy on the PCIe 2.0 16x and 8x and how they work in SLI.

I decided to stick with my monster of a chip 2700k and keep the Asus P8P67 since there is no reason to upgrade the mobo if I am keeping the chip...

I have my eye set on the 800 series graphic cards and was going to get two in SLI right off the bat..

However is there any draw back to the motherboard and its PCIe 2.0? Will the 800 series benefit from a PCIe 3.0?

If you were to run a GTX800 series or even a 700 series on a PCI-E 2.0 port, you will notice a drop in performance especially at higher resolutions

http://www.hardocp.com/article/2012/07/18/pci_express_20_vs_30_gpu_gaming_performance_review#.Ujb93n-E4vl

That's a pretty decent read on it, you will end up throttling your new GPU with just the pipelines.

Thanks for the quick and helpful response. I will take a look at that article.

So then I will need to upgrade to the Z77 series motherboard as they have PCIe 3.0 correct?

I can stick with the 2700k and still get the most out of the cards right?

Yes, that's correct

There isn't any need with going to a new chipset with that processor, the only time I would recommend going to the 2011 chipset would be if you were doing tri-SLi, in which case the extra PCI-E lanes and the x16, x16, x16 setup would give you another 15 - 20% in performance depending on resolutions.

If I were you, I'd have a look at the GA-Z77X-D3H, it's a great little board which won't break the bank and has great VRM's for overclocking. Coupled with the excellent features of the board I think you would be very happy.

Steer clear of ASRock boards, they have crappy VRM's and don't overclock as well.

I am an Asus guy myself.. well at least for my last 2 builds. I didnt have much of a problem.

One of my friends cheaped out and went Asrock and he had to send the board back twice..

Is there any real difference over the GA-Z77X-D3H and the Asus Z77 V or V-Pro other than the $50 difference in price.

Also since the 800 series isnt coming out till March would it be wise to wait till then? I know with computer component sometimes the price never drops it just goes discontinued..

None whatsoever,

In all honesty though, the Gigabyte boards use a better power system, IR power system I think it is. ASUS use their own bespoke power system.

Both are very good don't get me wrong, the gigabyte one is just a bit better. biggrin.gif

P.S I don't have a gigabyte motherboard, this isn't fanboism it's just facts.

Haha you didnt come across as a fan boy at all..

Only thing that concerns me which you can tell me if I am right or wrong is the Gigabyte board only hasve 1 pcie 3.0 or so it says on newegg. Where the Asus has 2 pcie 3.0... does both have to be 3.0 or as long as the one is 3.0 and the other 2.0 then it will get maximum performance..

I dont know much about SLI and how it honestly works other than performance not exactly doubling with a second card..

I appreciate you help very much!

It depends on the setup,

If you populate 2 PCI-E ports, you'll get a x8, x8 setup. If you only have one GPU it'll be a x16



If you look, the top one is x16, the next one is x8, they are both PCI-E 3.0

Just gonna throw this out there, the pci-e 2 lanes on that asus board will not be a bottle neck for the current or dare i say next gen of cards, after reading the hard ocp review there are some situations where the pci-e 3.0 lanes are a tad slower than 2.0...

that said, the newer boards are nice, but i would stick with ASUS.

Yea Newegg says 1 is 3.0.. probably a type o

I guess I will need more.people to way in if there's a bottle neck or not.. With 2 ski 800 series cards.. Probably 880 or 870s I would like to run games on max across 3 screens.. I mean why else have them..

Would that be something that bottlenecks them?
