Yea its a terrible card for gaming... It may have DX10 & Shader model 4 but it barely runs faster than the older X1300. Its a great card for the price when used for HD movie playback but gaming... not so much.
You'd get a decent performance increase (like 30% or more) if you snatch the nvidia 8500GT for like 10 bucks more.

EDIT:
Ummmm wow... I just found the best deal for a graphics card under $100 anywhere. Its a X1900GT for $89.99. This is ridiculous... its faster than a 7800GT or 7900GT and only slightly slower than ATI's previous king the X1900XT.
