PCI-E 2.0 and Radeon 4870 in a Asus P5B Tags: Radeon Asus PCI Express Graphics Product Last response: November 9, 2009 11:20 AM in Graphics & Displays Share moltar512 November 9, 2009 3:58:42 AM 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=N82E168... 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 More about : pci radeon 4870 asus p5b brockh November 9, 2009 4:33:17 AM It's fine, don't worry about it. pepperman November 9, 2009 4:38:39 AM 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. Can't find your answer ? Ask !
