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?

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

PCI-e 2.0 Performance
by greg.englar / December 15, 2008 5:04 AM PST
In reply to: Compatibility?

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?
by abdrewpd / January 2, 2009 3:30 PM PST
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

Would upgrading the motherboard to something like a

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 ramarc

In reply to: new mobo won't help

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
by syzop / January 5, 2009 4:59 AM PST

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
by abdrewpd / January 5, 2009 6:10 AM PST
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.
