I made a mistake, will I see any bottlenecking?

[skanlessflipboy]

The stupid description in newegg stated it had 16x PCI express, but that's only if you run it with SLi. I didn't thoroughly read the reviews until I had already purchased it and found out the mobo only supports PCI express 8x if using 1 card. I'm going to be putting a x1900xt and it's a gaming rig I'm building. Will this affect frame rate or bottle neck my graphic performance at all? I'm quite annoyed to have to return the damn mobo.

I think you got it backwards as an sli/crossfire mobo that have 2 pci-e slots will run x16 with one card and run both slots at x8 with dual cards. Just like my motherboard. What motherboard is that anyways?

This mobo is really cheap because I don't mean to go into overclocking, but I did want to jump into multi core processors.

My thoughts exactly.

Correct.

There will be no bottleneck to the X1900XT performance.

Since Anandtech has shown that the performance hit at 4X PCI-E is not that significant, then I wouldn't worry about it at 8X PCI-E.

@Pauldh, as wierd as it sounds and from what I've read the board does run a single card in 8X PCI-E as well as 2 cards at 8X PCI-E. :?

Of course this could probably be easily verified through Everest... :roll:

Fascinating...let us know how it goes.

 

[SirCrono]

I have the same mobo and I have a x1900gt, I haven't experienced any bottlenecking, so I think you are pretty much safe and shouldn't experience anything...as anoobis there said the gain of 4x to 8x or 8x to 16 is pretty much nil

No graphics card uses 8 lanes yet.

PCI-E x8 will be fine, u will recieve 100% performance.

 

[jkflipflop98]

The upcoming G80 is the only thing I know of that will even come close to saturating a x8 PCI-E bus. There's plenty of bandwidth to go around.

So ya, you're good to go.

 

[tool_462]

And that is still speculation, plenty of bandwidth there for your card.

I think it will be several years before we come close to saturating the PCIe, of which is future proof for the time being
