GTX 260 on a PCI Express x16 Mobo

[fp9200]

So I am thinking of getting this card.

http://www.newegg.com/Product/...x?Item=N82E16814130434

It's a Nvidia GTX 260 with 896 RAM

I currently have an 8800 GTS 512...couple of years old.

The problem is I have a 2 year old mobo too...only PCI Express x16...not 2.0.

I have read that there isn't really a difference and all the modern cards will scale back to the 1.0 framework, but I just want to be sure that I will be able to see the difference between this card and say a GTS 250 1 GB because of the bottleneck.

Any thoughts?

Thanks,
David

Here is my mobo in case you wanted to see anything specific.

I found this reply to a similar question over at Tom's.

Sounds like I should be good to go.

Yes, this question has been answered a million times.

Sorry for missing them.

That's not a problem. PCIe 1.1 will not limit GTX260. I am running 4890. You are still getting 4GB/sec bandwidth per lane which is plenty for a single-gpu card

I wonder how the future dx 11 cards will run on our P35s. Hopefully not too slow.

At least we'll have plenty of threads asking has I teh bottleneck.

Welcome to the forums O.P..

Felt like someone should say it after that rather frosty reception.

Hi everyone. First time for me here too.

So it turns out that GTX 260 2.0 x16 will give the same performance on either pcie 1.0 x16 or 2.0 x16 when not in SLI?

My system isn't performing very well despite my brand new gtx260. 1024screen size with all default COD4 is slow and very kind of choppy at points. Same with Batman Arkham Asylum.

I tested with nvidia 191.07 and now 185.85 drivers.

I don't know where the problem is. I thought it was in my ASUS g31 PCIe 1.0 mobo.

Here are my specs, and everything is brand new:
OS: Win7 and XP sp2

Intel Pentium Dual-Core e6300 2Mb L2,
MSI GTX260 896Mb OC -> http://www.newegg.com/Product/...x?Item=N82E16814127426,
ASUS Mobo -> http://www.newegg.com/Product/...x?Item=N82E16813131288,
4Gb 1066Mb Ram,
WD 640Gb SataII 32mb cache,
Rosewill Green Series 630W PS

possibly the e6300, you could try overclocking if you cant afford to upgrade

i would open task manager and check if cpu usage is close to 100% when playing games, not always accurate but can give and indication if the cpu is the bottleneck

Also check if all pci-e lanes are open in the motherboard bios, sometimes there is not a option if so dont worry it will be set to x16

 

[gneus]

should I completely forget about the mobo's PCIe 1.0 limitation then?

This is bugging me a lot. I can still exchange components. They are brand new....well ....3 weeks old mobo and cpu. I got a week more left to decide.

 

[Ares202]

double post

 

[Ares202]

yes

i run 1.0 x16 with a 4870 with no hiccups whatsoever on COD4 or any other game apart from crysis


even a ATI 5870 which is 60% faster than a GTX260 loses 2% of its fps when running at x16 (x8.0 on pci-e 2.0)

Our bottom-line on this subject is that there is every reason to be optimistic when opting for two of these accelerators on motherboards with two PCI-Express 2.0 x16 (electrical x8) slots, because the performance penalty between that and PCI-Express 2.0 x16 (electrical x16) is just too small.

MY cpu runs 77-80% during gameplay of COD4. switching between different setting in the graphic card menu does little to nothing.
Optimal graphic performance or all max, it is kind of choppy especially in a battle or open surface. Don't know what to do next.
Should I run some 3dMark tests and compare scores? Driver maybe? OS?

Your CPU is the likeliest bottleneck. That said, it should be fast enough...

teh necks they might be bottled so it needs to be asked

I started to think that it just because COD4 is an older game.
New games and all-max settings perform better by delegating all the work to the graphic card.
Older games are not optimized that well for new hardware, and that is why the choppiness comes.
I switched off AA on COD4 and it performs decent without significant quality loss. Screen resolution I don't think pushes the card at all. GPU temp does not go pass 54C.
I think the CPU is more that enough(especially for new games DX10, DX11). Pentium Dual-Core E6300 can be overclocked to 4Ghz. I wanna try some overclocking just for the sport

Go for it! Good luck, and there's plenty of OCing help to be found in the CPU forum.
