ati 9600xt or pro would smoke 5600fx. Runs at almost 200mhz higher core speed memory runs faster. But with the 5600 its cheaper so you can buy a 256mb card while with ati for that price you need a 128mb card but will still out perform the 5600fx but ati ill be deemed obsolete in about 6 years while 5600 might be at the bottem seeing as how games then will demand 256 colours but for now 9600xt i have it and it works wonders comes with a free hl2 coupon
