PCI-e 2.0?

by greg.englar / December 14, 2008 2:04 PM PST

Hey guys. I have a little hardware question. I am in the process of upgrading to a Core 2 Quad Q6600 with an EVGA GeForce GTX 260. The motherboard I am getting is an ASUS P5N73-AM Motherboard. My question is do most motherboards these days automatically have PCI-e 2.0 hardware? I checked on Wikipedia and it says its recent hardware but the video card requires it. As far as I have seen no motherboard openly says it has a PCI-e 2.0 slot. My motherboard has one PCI-e, and a PCI-e x16 slot. Any thoughts? The rig I bought (barebones) is here:

The stats on NewEgg say the motherboard is PCI-e 2.0 but then in the reviews they say it's not. Will this cost me performance from my videocard that says PCI-e 2.0 under the statistics?

Compatibility?

So does this mean that my video card will not work on my motherboard?

PCI-e 2.0 Performance

Ok, so I'm pretty sure I'm ok on this. However, will there be less performance from the video card on a PCI-e 1.0 as compared to a PCI-e 2.0? Also, if no single video card "requires" PCI-e 2.0 why is it listed on the requirements? Is it just a general term now? Thanks in advance.

will 2.0 mobo increase fps?

In reply to: PCI-e 2.0 Performance

I was wondering this as well. My fps in wow seems a little low.

I just recently bought a 9800 GTX

and I am using it on
http://www.newegg.com/Product/Product.aspx?Item=N82E16813186155.


Would upgrading the motherboard to something like a
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131324&Tpk=M3A78-EM

increase fps?

The rest of my system is:

amd 8750 triple core at 2.4ghz
4 gb ddr2 1066
500gb hd 7200 rpm
psu 550w
windows vista 64 bit

I have been looking everywhere for an answer, and most of the threads on most sites related to this topic are almost a year old. Am I bottle-necking my 9800 with a 1.0 slot? Or with a single card am I not utilizing the full capacity of the slot anyway and an increase is negligible?

I've seen many posts stating a 10-15% increase would occur, and I've read that nothing much will increase.

Thanks in advance for any help.

new mobo won't help
by ramarc / January 3, 2009 5:46 AM PST

pci express 2.0 has a higher top bandwidth but no single card available can exhaust 1.0's bandwidth. 2.0's bandwidth potential would only come into play with two-three-way sli/crossfire of the top end cards (dual 4870x2s or 2 or 3 gtx 280s).

wow is not a particularly demanding game so a 9800gtx should give you excellent performance. if you feel you're underperforming, read some a wow tweak/optimization guides to find the real culprit.

thanks for the reply. I didn't think I was bottlenecking myself, but I couldn't find a recent answer to my question.

The post above will explain my situation, but my graphics drivers weren't up to date. My fps wasn't horrible, I just knew I should have been sitting higher and the driver was the problem.

thanks again for the confirmation

Same type of issue

abdrewpd : What FPS are you getting in WOW? because mine really suck and i'm trying to figure out what video card I need to get and I was planning on getting a Nvidia 9800GT.. My mobo is only a 1x so I dont have PCIe2.0 .. so I know the card will still work however; will I still increase my FPS greatly or will they be the same? My friends specs are simulare to mine and are getting 60FPS with a better video card..

My old system and was getting around 9-10 FPS
AMD 2.4 AM2
2gigs ram 400mhz dual channel
Nvidia 7600 PCIe1.0

upgraded before xmas to : and getting a whopping 17-20FPS
AMD 3.2ghz AM2
4gigs ram 800mhz dual channel
Nvidia 8500 PCIe1.0

50-100 fps, i have seen it up to 164 in certain instances

In reply to: Same type of issue

I had just built this computer about a week ago now, and I was having motherboard problems (doa) and I had to repair/reinstall windows after getting a second one. After doing so I had forgotten to update my video card drivers.

I'm actually playing wow now, just alt tabbed back in and I am sitting at 69-70 fps with everything on high, 1440x900. The shaders and view distance are both at half. I hit about mid 20s-mid 30s in dalaran with zero lag whatsoever.

If you can spend the extra money you can't go wrong with the 9800 gtx, but the gt is seems solid.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
