PCI-E 2.0 and Radeon 4870 in a Asus P5B

I just ordered this:

XFX HD-487A-ZWFC Radeon HD 4870 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card

http://www.newegg.com/Product/Product.aspx?Item=N82E16814150436


but i just noticed it says "PCI Express 2.0", which probably isn't included on my P5B Deluxe Asus mother board, which i bought 3 years ago...

Wikipedia says they are backwards compatible, but who knows if that is true

I just ordered tonight and it's not too late to change my mind...

will this card work with my Asus P5B Deluxe PCI-e x16 card slot?

Thanks

  1. It's fine, don't worry about it.
  2. The card will work just fine; PCI-E is indeed backwards compatible, so you don't need to worry. Make sure you uninstall the drivers from your current graphics card before installing the new one and you'll be fine.
  3. Thanks guys!
