^+1 for ATI heirarchy.

A 5670 is ok, it'll run most games at 1920x1080 with moderate to high settings... Crysis probably will be ok at medium while Fallout 3 can probably be pretty high for example. And yes that's a legit card. My only issue with it is that it doesn't blow the air out the back because it's a single slot so you need good case cooling with that one.
