5870 2GB on X8 lane is okay?

post #1 of 4
Thread Starter 
Guys, how bad will it be if I just use the 2nd PCI-E Lane (x8 electrical) of the ASUS Z68 V PRO?

The first PCI-E Lane is x16 electrical but if I use the provided USB 3.0 bracket, then I will not be able to use that lane. The only next choice I have is to use the 2nd PCI-E Lane but is only x8 electrical.

What do you guys think?

Thanks so much in advance.

Would appreciate "graphs or articles" as well If possible only.

You might notice 1%-2% performance decrease at most.

Sorry no graphs to find it out, some other more helpful members I'm sure will give you what you desire.

You can't put the USB on the X8?

You shouldn't have a problem unless you're trying to break records, barely any loss especially for a single gpu card.

Only looking at 2-3FPS loss at most.

(Not sure how this bracket is in the way...)
