256MB video cards for AMD Athlon 64 3400+

Performance, Performance, Performance!!!              
      I'm tring to find the best 256 MB video card for the Asus k8v deluxe or k8v deluxe-se motherboard.  I want to stay in the $400 area.  I want the best video card for watching and recording DVD's, high performance gaming, and video editing ,on not only my PC monitor, but my 50" big screen TV, and soon a  60" big screen HDTV.  Should I stick to the same manufacturer as the mainboard?
