Can a PCI-E 2.0 GPU work on a regular PCI-E x16 mobo?

The reason I ask is that I just installed an EVGA E-GEFORCE 9800GT 600MHZ 512MB 1.8GHZ 256BIT DDR3 on my P5Q Pro and it works beautifully, plus the price was right at $117 ATT! ^*^ Ignore the price you see today.

This price beats anything hands down that I can find today for an 8800GT which is an equivalent card to my knowledge. Since I got the 9800 so cheaply, I assume the sale price will be repeated soon enough and I'm a patient person.

The board I'd like to install the 9800GT on is an A8N-E which says nothing about PCI-E 2.0 in the manual. My main objective is the most bang for the buck as this will only be a dedicated folding machine plus a server.

Thanks all.

 

Is this the one - http://uk.asus.com/products.aspx?l1=3&l2=15&l3=0&model=455&modelmenu=1 ??

It seems strange that the website doesn't say what type of PCI-E slot it is, I'd imagine it would work fine. Perhaps contact the manufacturers themselves and ask?

 

Yup, that's the board. Ya I sent a mail to eVGA so I'll see what comes of it. Maybe I'll just get an 8400 or something at half the price and leave it at that. Thanks man.
