Bottlenecks Pci-e + Cpu

[Matthew12106]

Just a quick question about gpu performance. I'm going to be upgrading to a gtx 800 card which is awesome. My motherboard has a pci-e 2.0 slot rather than 3.0 slot, and I'm thinking about performance. Now I already know from previous posts and research that barley any card can use up the full bandwith of pci-e 2.0 x16 (290x comes close) but if that's the case how come there is still (although minimal) a performance hit.

Also just on a side note I think the answer to this is obvious the 8350 won't bottleneck any hide-end gpus right

The 8350 will bottleneck high end GPUs.  If you have a 60Hz monitor, the bottleneck won't be noticeable, but that doesn't mean a bottleneck is not there.

[MasonV]

That doesn't look like a bottleneck, that is literally margin of error right there by the looks of it, and it goes both ways.

I've noticed a difference in graphical performance from switching to a pci-e 3.0 board and a 4690k from an a10 5700 apu and an asus fm2 a85-v pro motherboard which was only pci-e 2.0. The only thing that has changed has been the cpu and mobo, same graphics card. I now see almost no screen tearing at all, and almost no framerate drops.

Ok now that that is over Really the 8350 seems pretty high end I mean like in some games will it cap because of the cpu

....

That performance difference has nothing to do with motherboard, its the fact that you moved from an APU to a real CPU.

I highly doubt it unless the game is both CPU and GPU intensive or you're running a ridiculously lopsided setup.

High end back in 09'.  Its a very old processor, and the majority of games will benefit greatly from having strong Intel cores, especially the minimum framerates which are the most important.  If you play games such as: Skyrim, Diablo III, Starcraft, DayZ, Any Indie Game, Any MMO, League of Legends, Assassin's Creed, etc.. they will not run as well on an FX processor.  Some games worse than others.

Ok that kinda sucks but I don't think it's worth it to upgrade my cpu. Let's just say the gpu at full potential l can achieve a 100 frames as in with no bottlenecks if you pair it with a 8350 what kind of frame rate would you get

Depends on the game and the GPU.

I was using the same gtx660 on both systems, wasn't using the apu for graphics (made the noob mistake of buying an APU)

Yeah I guess but if you go to 2:38 on this video which are the gaming benchmarks it doesn't seem that bad compared to a 4770k

Do you think it's still worth it to get a high end card like the 880 when it comes out

Most games I play are like bf4 titanfall Tomb raider saints row 4 Nosgoth which is what I'm playing now stuff like that

For those games, doesn't make sense to switch.  Stick with what you have.

 

I'm not quite sure what Nosgoth is, it sounds MMO-Like.  That may run kind of choppy on an FX.

No it's just a 4v4 Humans vs Vampire combat game it's in beta right now but you can become a founder for like £3 It's allot of fun

For 60hz monitor you are good to go with the 8350. Above 60, it's gonna be disappointing.

 

Consider changing to blue team if you take the next step and buy a high refresh rate monitor.

I think I'm happy with 60hz I mean I never tried anything else but when you say that are you basically saying it will achieve higher the 60 fps or what do you mean

[Vrbas]

It's not worth spending $300-500 on a new CPU/Motherboard, stick with what you have until the next gen CPUs come out. Since you have a 60hz monitor just focus on 60FPS which the FX will be fine at achieving in the games you play. 

 

As you can see in the benchmark the Titan doesn't even bottleneck with 2.0 x8, it will be highly unlikely that the 800 series will bottleneck 2.0 x16. Just wait for some benchmarks until you purchase a new card you want.

From some research it's only going to be a very small diference anyway

Exactly not worth the money that can be spent elsewhere. 

[Khraft]

Is everyone forgetting that the 800 series cards are supposed to get DirectX 12? Ofc, it won't affect games already made but I would say that your 8350 would benefit in the future.

[Sintezza]

...

Do you realise that some SLI systems run at PCI-e 4x and they don't bottleneck? (ignore poor scaling)

 

Do you realise that Sli not work on 4X ?

8x is minimal

[Sintezza]

http://www.overclock.net/t/819348/16x-16x-vs-16x-4x-gtx-470-sli-comparison

 

THats not possible.

sli does not work on X4, only on 16x or 8x

You can only crosfire on 4x.

 

But in the case of that topic they talk about an old GTX470, maybe it worked on 4x with those old cards.

But the newer ones definitely not.

 

Why do you think that for Sli support on intel you need a Z series chipset board? Right because you get 20 pci-e lanes x16/x8/x4 you are able the run a Sli at 8x. H series chipset boards lack on the support of sli, because you only get an X16 /X4 slot.

 

Same story with AMD

970 chipset only X fire, cause X16/X4 slot.

990X - X16 /X8 /X4 so you could run sli on 8x

990FX - X16 X4 X16 X4 you can run ali on 16x

 

Same stupid statement that i read allot: "you should go intel Z87 /Z97 over AMD 990FX because 990FX is an old chipset and only has pci-e 2.0...."

But those people dont same to realise that the 20 pci-e 3.0 lanes you get on Z87/Z97 are just as fast as the 40 pci-e 2.0 lanes you get with the AMD 990FX chipset. it doesn´t make a jackshit diffrence.

Unless you buy those realy over expensive Z97 boards with a useless plx chip, gimmicky thingy.

I have no idea what you just said.
