AMD/ATI Video Driver Won't Download?

So I had several video crashes over the last few days so I decided download updated drivers for my x5850. Running windows 7/64 on a quad core i750. AMD drivers site says this is a legacy device. It also shows "vista" and the wrong part numbers so their site is messed up (using pull down menu's I selected my gear/OS) and yet it refers me to drivers for a device thats about 7 years old, instead of the one I actually requested for
