Do I not get PCI 3 if I put a SB chip in a Z77 board?

[Cythx]

PCI 3 is looking to be real important for multi-monitor multi-GPU setups, so if a SB chip will block me from using the PCI 3 functionality on my Z77 board, I will deff. not be buying SB.

Thanks.

K well I'm going IB then.

PCI 3 is not really important for single monitor single GPU setups.

PCI 3 is incredibly important for multi monitor multi GPU setups. I have a U2711 and I'm planning on expanding, when I do, I will need to go from a single 680 to 680 SLI. When this happens, PCI 2 would be a huge bottleneck.

A huge bottleneck? Find me a GPU that gets "hugely bottlenecked" by an 8x PCIe 2.0 slot?

I guarantee that you won't.

A single GPU on a single monitor resolution? No, there isn't one that will get bottlenecked under such circumstances. However, I never said there was such a case.

I think you need to re-read what I said, and more carefully too.

I was talking about a bottleneck in a setup including 2 high end GPUs like the 680 with multiple monitors, for example 3 1080p screens.

Setups like those is where you'll see PCI 2 bottlenecking, according to several people who have multi GPU multi monitor setups and have tested both PCI 2 and PCI 3.

I think the issue was more to do with the term 'huge' bottleneck. Which you clearly won't have with x8 PCIe 2.0.

Way to go on the ultra defensive though

After looking at the graphs below, can you please show me where it is so clear to you that you clearly won't have a huge bottleneck?

I would really like any sources that bench SLI 680/7970 with multi monitor setups such as the ones listed below.

This is 'huge'. If you want more information, talk to Vega, these are his results.

The bars you will want to be looking at are the 2nd and 4th set, as they are the multi monitor setups.

This is also 'huge'. If you want to contact the person who made the graph, ask me and I'll find out where I got the graph.

Are you not reading the graphics correctly?

32>53, 62% increase
69>97, 41% increase
52>78, 50% increase
40>61, 51% increase
79>108, 36% increase
56>85, 52% increase

'Unless you plan on getting 4 cards'... I assume this is a mistake because you did not read the 2nd graph correctly. If you did, you should mean 'Unless you plan on getting 2 cards'. Plus, I have a single 2560*1440 screen and I'm expanding on this soon.

Holy **** you must not be able to read

and then you respond

> unless you plan on getting 4 (you should mean 2) cards or some crazy high res monitors, then i cant say claiming the bottleneck is gunna be HUGE is an accurate statement.

When did you read I was NOT getting a multi monitor setup and that I was NOT getting 680 SLI?

 

[Cythx]

4 way SLI? Not exactly a representative benchmark.

The second graph is better and yes, it's still not huge. No-one disputing there's probably a bottleneck but come on - rein in the rhetoric.

I will also admit the 2nd graph is more represntative of what I will be experiencing, but:

32>53, 62% increase
69>97, 41% increase
52>78, 50% increase
40>61, 51% increase
79>108, 36% increase
56>85, 52% increase

How is that not huge?

 

[Cythx]

thats not important as he has read it somewhere so it has to be true.
trust me, not worth it he has in his head that PCI-e 3.0 is going to make his pc superfast and PCI-e 2.0 will run like a dog.

If you would like to show me any benches that prove me otherwise I would gladly read them and consider them against my intention of purchasing a 3570k.

Please, show me those benches.

 

[Cythx]

BECAUSE ON A Z77 MOBO YOU WILL NOT GET 16X 16X SLI

It will x16 x8 right? Will this will make the difference insignificant? I'd like to see some benches before I consider the difference insignificant.

Unless going from x16 x16 to x16 x8 will reduce those % figures by 10-20%, it'd still be a huge increase for me.

 

[Cythx]

It will be x8 x8 SLI PCI 3 on z77 mobos... x8 pci 3 is basically pci 2 x16 BUT the evidence your showing is PCI 3 16x 16x...

Ah, thanks. Time to look for reliable benches on PCI 3 x8 vs PCI 2 x8. That'll be tough to find.

 

[Cythx]

So you won't actually see that major a difference from PCI 2 to PCI 3. Like everyone else has been saying.

Didn't you just explain that in your previous post?

 

[Cythx]

Key to this is the source, without that the graphs are worthless. This is one case where a decent scientific method is required.

1st one, ask Vega about his methodoly.

2nd one, go here to found out, the board used for that bench was the Asus P8 Z77 WS

Yes but clarifying a point helps sometimes so it's best to do it just incase.

thanks for being so considerate.
