Featuring a solid bundle, the XFX 6600GT AGP leads the pack in availability, several online sources selling the card around a $225 price point. How does the 6600GT AGP compare to its big brother? Should you use this card to upgrade your system? Best described by the phrase "more than enough for most of PC users", the 6600GT had sufficient performance to keep me from wanting to put the 6800GT back in my system every time I fired up Half-Life 2 or Doom3.
